D. 2-1  SECTION 2   INSTALLATION 2.1  GENERAL INSTALLATION INFORMATION 2.1.1 Safety Precautions It is the task of the site supervisor or construction manager to make available the materials supplied by THALES Italia s.p.a., independently procured special materials and tools. For every site, strict attention should be paid to safety regulations issued by the local authorities. 2.1.1.1 General rules The following rules should be observed for prevention of accidents: -  Consumption of alcohol in any form is forbidden on the installation site. -  Drunken persons or those under influence of alcohol will not be tolerated on the installation site. -  Protective goggles and safety gloves are to be worn when work is being carried out on batteries. Rinsing water, soda and several cleaning cloths should be available. -  Sturdy shoes, safety gloves and safety helmets are to be worn. -  Protruding nails, strips etc. must be removed immediately. Ladders and planks must always be carefully checked before use. -  Do not tread on protruding plank sections. -  Never leave objects on scaffolding or ladders. -  Scaffolding or frames are to be erected sturdily and must always be tested before use. -  Test electrical devices and extension cables for accident safety. -  Remove fuses before carrying out work on mains. -  Wear protective goggles when carrying out sanding or drilling operations. -  Sand off burr from chisels and punches in good time. -  Test striking tools for tightness of fit. -  Do not put pointed or sharp objects into working-clothing pockets. -  Jewelry such as chains and rings should be removed when working on building sites - especially when working with electrical devices. -  Always keep escape routes clear. -  Every employee on an installation site should know: •  where the First-Aid box is kept •  the telephone number of the nearest casualty doctor and eye specialist •  where the fire extinguisher is kept •  the location of hazardous areas on the way to the work place, or at the work place itself.  Damage caused by animals is highly improbable. The door of the shelter or equipment room should be locked in the absence of the personnel.
955 900 031 C   DME 415/435 -Technical Manual Vol. 1-Section 2 - Installation 2-2 THALES Italia S.p.A.- A. S. D. Vers. D, September 2005  2.2 INSTALLATION PRELIMINARY  The operator must perform the following operations when installing the beacon:  Select and prepare the site;  Unpacking, Paging and shipping;   Typical installation  • ground the equipment; • connect the power supplies; • connect the antenna. • I/O connections The following connections may also be necessary, depending on the beacon configuration selected and the options used: • connection the facility with associated equipment; • connection with other equipment.  2.3  INSTALLATION SITE SELECTION The area in which a DME is to be installed is determined by the responsible Civil Aviation Authority according to the international air traffic regulations.  The area is dependent on the type of obstacle. Also clearance and runway configuration (e.g. overrun, clearway, stopway) in case located in terminal area. The following site selection guidelines are general recommendation and only guiding values for information. The exact values are locally dependent decisions, which are made during installation. They are computed with formulas, which take in account of terrain, obstacles and other. See Appendix "A – DME Antenna Siting Area Criteria", on this volume. The installation is determined by means of a site survey at which a surveyor must always be present.  THALES Italia s.p.a.  is able to provide engineering consultants on site for this survey.  The DME installation area selection depends on the following using conditions:  1)  Terminal Area beacon  a)  DME (substituting or integrating MARKER functions) placed with ILS equipment In this case, DME antenna, usually directional antenna, is mounted on Glide Slope antenna mast and the DME equipment is installed into Glide Path shelter.  b) Stand-alone DME with omnidirectional antenna on its own mast and equipment installed into a suitable shelter. The area is dependent on clearance and runway configuration.  2)  In route beacon  (External zone site and normally far away from terminal area), with or without associated VOR equipment: see Appendix "A – DME Antenna Siting Area Criteria", on this volume
DME 415/435 -Technical Manual  Vol. 1-Section 2 - Installation  955 900 031 C Vers. D, September 2005 THALES Italia S.p.A.- A. S. D. 2-3  2.4  EQUIPMENT SITE LOCATION   The ground beacon may be installed in a control room or inside a shelter, which complies with the environmental temperature, humidity and pressure values listed in Section 4. Bear in mind that the equipment has the following overall dimensions: −  height: 1730 mm, −  width: 580 mm, −  depth: 635 mm cabinet code 297509007or  610 mm cabinet code 297509004 the amount of space around the equipment must be as follows: −  more than a value  between the rear part of the beacon and the wall or any other piece of equipment, to allow the operator to open the rear door of the equipment. Make it possible support the back part of the cabinet to a wall, in as all the operations of cables and connectors assemblage, could be performed on front.  −  a minimum of 30 cm between the top of the beacon and the ceiling of the control room or the shelter to leave space for the external connection cables and to allow access to the antenna connector and to the antenna probes connectors; −  a minimum of 60 cm between the front of the beacon and the wall or any other piece of equipment, to allow the operator to open the front door. The base must be able to support the total weight of the equipment (approx. 200/230 kg including the optional modules) within the range of dynamic stress envisaged for the equipment.  The beacon does not normally need securing; if it is to be secured to the base, however, four M12 bolts should be used and their fixing holes. 2.5  UNPACKING, PACKING AND SHIPPING;  The equipment should be unpacked as soon as possible in order to check that it is complete and intact. The place of storage used for any intermediate storage period must be dry. The temperature range specified in the technical data section 4 must be conformed to. The check list is inside the packing to which to refer.    The DME beacon and modules will be packed according to the national and international standards. The packing procedure may be slightly different according to the way of shipping or to the destination country.  2.6 TYPICAL INSTALLATION Figure 2.8 shows all the connections for beacon installation. Should this use an I/O system provided with the LCSU unit in standard configuration; this figure also illustrates the characteristics of the cables used for installation and provided by the manufacturer, as listed in table 2.1. The main characteristics of installation cables are on figures 2.1 to 2.7. The reference item is shown on figures, internal at a circle. WARNING  Before connecting the cables check that the mains lead is dead and that the battery is not connected (the breaker of mains and battery, on external electrical switchboard, must be OFF).

Battery connections typical Battery type and size depend on requirements. Suggested batteries for back-up power supply must have the following characteristics: -  Output voltage: 48 V nominal (four 12 V unit serially connected: see fig. 2.14); -  Nominal discharge capacity: 50 A/h (this capacity ensures a time duration as at para. 4.10 of section 4); -  Low maintenance types or sealed types; - Low self-discharge; -  Long life: >4 to 5 years; -  Temperature range:   -20 to +50 °C; -  The charge from the equipment, at constant voltage, is typically: 2.25 V/element. These required characteristics should be completed by technical information from the battery constructor. CAUTION  The low maintenance battery group must be placed in a low-ventilated environment, while the other sealed types, may be installed everywhere. In any case, follow the battery constructor’s instructions. 2.6.3.1.1  Battery duration time (on 230Vac black-out)  The battery 50A/h (at end of 42V voltage), are the following:   DME415=20h - DME435=12h for TX2 stby, TX1 en service, and radiate 800 pps   DME415=18h - DME435=10h for TX2 stby, TX1 en service, and radiate 2700 pps   DME415=17h - DME435=7h pour TX2 stby, TX1 en service and radiate 4800 pps    NOTE: With battery 12 mounts old the back up period duration is typical degraded of 10/15% (see also the technical information from the battery constructor)

D. 2-15  2.6.4.1    Antenna coax cables-Attenuations and delays    The interrogating signal from the aircraft received on the beacon antenna, comes the antenna connector SK1 (equipment input/output RF) with a delay ΔtRF which depends on the antenna coax cable.  This delay, indicated in μs, is given through the following relation:  where:  -  L: Cable length expressed in m  -  P: Relative propagation velocity (for LCF 1/2" cable, typical value:  88%) -  c: Light velocity (300 m/μs)  The low loss "LCF 1/2 inch" standard cable, has a delay of about 0.004 μs/m and an attenuation of about 0.073 dB/m. The signal received in antenna comes the beacon receiver after a ΔtRF delay, is processed and, after the reply delay (introduced by the transponder), returns to the antenna from where it is transmitted with an additional delay ΔtRF (introduced by the antenna coax cable). If it is supposed that the beacon uses a "X" channel mode (50 μs reply delay), the total delay of the reply signal, generated by the antenna output system, will be:  Rvel. = ΔtRF + 50 μs +  ΔtRF = 2ΔtRF+ 50 μs The measurement of the reply delay value and its automatic compensation, in 25ns steps compared to the fixed value, is performed by the monitors through interrogating pulses (Pilot pulse) sent by the transponder receiver. The calculated value of the delay and the cables loss according to their length is shown as an example in the following table 2-3):   Table 2-3 - STD Coax cables  Coax. cable Parameter Description Type Length  Value Monitor Cable Loss   Loss of monitor coax. cables probes for  monitoring  LCF 1/2"  25 m  Approx. 2dB Antenna Cable Loss  Loss of antenna coax. cable  LCF 1/2"  25 m  Approx. 2dB Delay time   Delay of antenna coax. cable  LCF 1/2"  25 m  Approx. 100 ns   2.6.4.2  Data entry calibration procedure for “EXTENDED CONFIGURATION” Figure 2.16a) shows an example of typical installation with equipped standard cables.

Remark:  The peak power output calibration procedure of the TX100 ad TKW modules is described on section 5 -MAINTENANCE- para. 5.3.4 and 5.3.5 of this volume. This procedure must be carried out during the installation, in the event of substitution of module TX100 or/and TKW and also in case the channel change.  c   P L   t RF× = Δ

Unplug the antenna cable and to connect the "peak power meter", as in fig. 2.16a, to the antenna connector. Switch to “OPERATING” mode, take notes of the reading of the power peak meter. b)  Restore the connections of the antenna cables. With TX main in OPERATING and on window “EXTENDED CONFIGURATION – Mon. 1 Power Adj.”  Enter, if necessary, a preset value from -100, 99, -98 ......to ..... +98,+99,+100 (Nr. 1 step by step), in order for the measurement reading on “Executive monitoring: Peak Power Output” to be the same (±2%) as the one indicated on the external “Peak Power Meter”, previously noted. c)  Repeat point b) for “Mon. 2 Power Adj." on window “EXTENDED CONFIGURATION  2.6.4.2.2 Measurement calibration of the TRANSMITTED POWER (radiated)  a)  TX main on antenna in OPERATING. On window “EXTENDED CONFIGURATION – Monitor Cable loss” enter the value, measured or calculated, of the monitor probe cable loss (for standard cable see table in previous para. 2.6.4.1) b)  On “EXTENDED CONFIGURATION – Monitor Probe Coupling” enter the value of the coupler at the operating frequency, a detail that is pointed out on the antenna features. For the model FAN 96 and FAN 88 the coupling values of the probes are shown on a table enclosed to the package of the antenna (for antenna FAN 96: typical value 20dB ± 3dB) c)  On “EXTENDED CONFIGURATION – Antenna cable loss” enter the value, measured or calculated, of the antenna cable loss (for standard cable see table in previous para. 2.6.4.1) d)  The measure indicated in “Transmitted Power”, in theory, should be: [“Peak Power Output” – Antenna cable loss] in Watt Some significant power ratios and loss percentage are calculated as per the following table 2-4 : Table 2-4 - Loss of STD coax cables Ant. cable loss: dB  Ratio  Loss    % -3 0,5 50 -2 0,63 37 -1,5 0,708 29,2 -1 0,78 22 -0,5 0,89 11 -0,1 0,9772 2,28 Example: with STD cable (25m – LCF ½”) the reading in “Transmitted Power” must be: 1)  for DME 415 with 110 W in Peak Power Output: 110 – (110 * 0,347) = 71,83 W    2)  for DME 435 with 1050 W in Peak Power Output: 1050 – (1050 * 0,347) = 685.6 W  e)  if the reading in “Transmitted Power” is over ± 2% compared to the value mentioned in point d), vary, step by 0,1dB step , the data on window “EXTENDED CONFIGURATION – Monitor Probe Coupling” (or in “Monitor cable loss”) up to the limit of ± 2%. NOTE 1: The sum of the values in dB [Monitor Cable Loss + Antenna Probe Coupling + Antenna Cable Loss] must be >20 dB and <33 dB, otherwise the data will refused. NOTE 2: Values in “Transmitted Power” of each monitor can be adjusted within ±10%. Difference of measure  of the values in "Transmitted Power"  between the two monitors due to different attenuations of  the coaxial cables, couplers and internal coax cabling, can be corrected with the trimmer P6 mounted  on module MON (shown in fig. 2.17), in order for each monitor to read measurements that are as equivalent as possible.

D. 2-35  2.6.8  Associated Facility Interface Electrical interfacing, i.e. identity association can be easily performed as well, by means of a highly flexible interface board (AFI), inside the DME cabinet. The DME ground beacon can be associated to VHF equipment such as a VOR or ILS. In this case, the beacon must be equipped with the appropriate AFI interface module. The DME can operate either as master or as slave in the association (software configurable), according to the VOR or ILS capability and to system requirements. A cable with a single connector fitted is supplied for this connection. This connector must be connected to connector SK4 or SK5 (called AF1 or AF 2 ASSOCIATED FACILITY) on the I/O panel of the equipment (on top of the cabinet). The other end of the cable must be connected to the associated VHF equipment. AF1 or AF2 are selected by means of an external switch (e.g. by Control tower room): see applications in figure 2.29. In default condition, is enabling the AF1 connector.  The connection to associated equipment of the identity and beacon status signals input and output, is shown in the figure 2.29 (application) and the block diagram is shown in figure 1.30 (section 1 - General information).  The lists of the pin signals on connectors SK4 and SK5, on top end I/O panel, are in Tables 2-9 and 2-10. It is possible change the current source (source external or source internal) rotating 180 degree the 8 pin DIL header plug, shown in figure 2.28, of the module AFI layout for a correct positioning of the links Figure 2.30 gives a few association examples with equipment associated.

The configuration, alignment procedure and the maintenance are performed with a locally connected PC via a user program "WINSV Supervisor" installed on a PC (typical connections example in section 1 on Vol.1 of this technical manual). In the normal case standard of remote operation, is carried out via a control interface, connected at a Remote Control and Status Indicator unit (typical connections example in section 1 on Vol.1 of this technical manual).  3.1  LOCAL CONTROL AND INDICATION PANEL The local controls and indicators are to be found on the front panel of INC Module of the LCSU unit only, located at the front door.  The Control and Indication Panel is subdivided into the following fields: •  MAIN STATUS  • DETAILED STATUS • COMMAND • CONTROL • STATION  • LCSU   The individual fields contain indications and keys. Only those indications currently in message status are lit up and thus legible. This ensures that misinterpretations are avoided. The meaning of the indications and keys in the various fields are described in the following paragraphs. These controls and indicators are listed in tables 3-1 and shown in figure 3.1.

In general, this mode is used when the user is on maintenance PC or on RCSI in the site.  Ö Dedicated call  (direct call) The connection between the DME and the user is made trough a Modem programmed in ORIGINATE mode. In general, the user is a RCSI. (modem type: desk external LGM Internal (only LOGEM 28,8)  The parameters needed to make the configuration are: • Baud rate 1:300, 2:1200, 3:2400, 4:4800, 5:9600

Ö Switched line The connection between the DME and the user is made trough a Modem programmed in Switched  mode. The parameters needed to make the configuration are the following: −  Additional port (Ad) This is a communication port used in addition to the other when the customer requires the redundancy of the communication line. Therefore is possible to communicate with the same user on two different lines. The additional port is used only if the first port is wrong.  A 0 value disable the line redundancy. −  Modem kind  External:  a desk Modem LOGEM:  an internal Modem (only "Logem 28,8" is supported). − Phone number Phone number of the user: 18 characters are allowed − Call logics: they define which the LCSU must call the ignore user.  Syn,  All, Ctr, Hs, Dual user: definitions described status above Ö Party line. This kind of line is used when the DME is collocated with many equipment (in general these of an ILS). All linked to a remote user using a multi point connection. The parameters needed to make the configuration are the following: − User Mater/Slave It defines which is the Mater of the communication, in general the user. A "M" means user is master (this is the suggested value), an "S" means user is slave.  − Slave Address It define the address of the slave (from 0 to 9). If the user is Master, this is the Address of the DME, else is the Address of the Remote  The value to set depends on the configuration made on Remote Site. The final data for each “user” option considered, has been entered in fig. 3.7 video page. The data is shown in sequence each time the operator enters the correct reply based on the requests sent out by the program (in bold type). If the operator gives a wrong reply, the sequence must be repeated starting from the request for “user number”. The control priority is intended as the possibility to exclude the operators of the subsequent “user” from the equipment control (an operator excluded by another with higher priority has to wait until the latter has finished before being able to have control of the equipment). The priorities have the following order of importance: 1 = LCSU 2 = Local PC 3 = Remote PC and any other RCSI/RCSE The higher priority is assigned to the “user” associated to the lower number

In such way, the LCSU looks the signal in alarm when the wire is not connected to.  − Command The input is coming from the keys on the Control Panel or from an external panel. To the signal are associated: •  An Internal Number, defining the pressed key 0=Request/Release 1=Equipment ON/OFF 2=Changeover •  The equipment identifier This number must be kept from System Overview screen. For DME 415/435 is always =1 − Lamp test This function define where is the Lamp Test key of the Control Panel. No other information are required as the other keys on the Control Panel. − Buzzer Silent This function define how the silent key must be managed. The only information needed is the referred equipment identifier to link to the silent key to the DME, therefore the identifier, as explained before for the Commands, will be=1. − Selection This function defines the management of the "Select key" which allows the operator to enable the "Detailed" section on the Control Panel. The only information needed is the "Sharing Identifier" defining the equipment to show in the "Detailed" section. In this case the Identifier is given by the column on the Control Panel when is the Selection key. In the DME this Identifier is always =1  −  Parallel internal Input This function define the management of 12 Input Signals inside the DME cabinet carrying information about mains and battery modules.

D, September 2005  3.2.2.6  Modem Configuration When using a modem for connections to the different units at a distance from the site where the beacons are installed, it has to be suitably configured for the specific service it is prepared for. Modems used for the various connections have to operate: −  in the phonic band (300 - 3400 Hz); −  on 2-wire dedicated or switched lines; −  in accordance with CCITT V21, V22 and V22bis standards; −  with AT protocol controls; −  with asynchronous mode communication. The modem configuration is prepared modifying its internal parameters  through AT controls. The configuration may be in two ways: 1.  Connect a PC to the modem using a terminal emulation program; it is then possible to modify the relevant parameters using a series of AT commands. This type of operation requires detailed knowledge of the modem parameters. 2.  Connect a PC to the modem and run the program typing in <modem mdfile.mdm>, then press the ENTER key. The  modem.exe program imports the configuration data from the mdfile.mdm file and sends it, in sequence, to the modem, verifying each time that it has been accepted correctly. The UTIL - Configuration Utility diskette contains several examples of *.mdm files previously prepared for some types of modem. The AT standard does not guarantee that all modems have the same commands, therefore it is necessary to prepare the *.mdm files for each specific modem. These files can be edited by the user, starting from one of the existing examples and using a normal text editor the desired parameters can be modified to obtain the suitable file. The main parameters to be configured in order to work correctly with LCSU are: AT&L0(1)  line type (dedicated or switched) ATB0 CCITT  full duplex standard ATFn     line speed (n defines the standard and depends on the modem used) AT&C1   Interfaced criteria forced to work state ATX0      Blind dial without busy or ready tone recognition AT&D3 DTR  transition ON -> OFF cause modem reset AT&G0   Guard tone disabled ATS10=40  Carrier faulty disconnect delay time 1/10 s ATT(P)   Tone/pulse dialing ATS0=2  Number of rings (only in switched)

D. 3-39 3.4 I/O FUNCTIONING The equipment can be controlled form the site where the beacon is installed (local site) or from a remote station (remote site). At the local site, the equipment can be controlled thorough direct use of the controls on the LCSU Front Panel or using a PC (Personal Computer) connected to the PC RS-232 connector or SK1 of I/O panel.  Usually, the priority of remote connections is lower than that of the local connections (default condition) At the local site equipment control, priority is: Control Panel and lastly PC connected to the LCSU unit.  The local operator can activate local commands using the REQUEST RELEASE button, thereby disabling any commands received from a remote operator. The indications remain active on all the remote stations connected. From the remote site, the equipment can be controlled via a PC connected directly to the LCSU unit through a switched or dedicated line modem. Operation mode Intrusive or detailed, Line monitoring, Maintenance and so on, are allowed only using a PC (in Local or Remote site) connected in any mode (directed, trough interposed RCSI/RCSE/MCS, Switched line and so on)   A detailed description of the permissible operations of the PC with supervisor program is used, is given in next paragraphs and APPENDIX sections.   3.5  USER SOFTWARE INSTALLATION ON PC 3.5.1 General The use of usual PC standards and operating systems ensures a familiar operating environment for the user.  The most important status displays and control functions are also provided on the station’s front local control unit (LCSU) so that operation is easy also without a PC system connected. Using a PC connected to connector SK1 - RS-232 (PC) with a user program (WINSV, WINDME400 or MCS) all informations are provided. The dialog software represents the core of the operation devices. All control, monitoring, and maintenance functions are represented on the screen in colors, in the form of menus. They are carried out in control windows by means of functional keys or mouse control.  Via an online help function texts explaining functions or screen masks can be requested and, if required, printed out. The user software interprets the operating data input by the operator, checks it for plausibility, formats it into a specified format, and transmits it to the respective system or subsystem components (monitor, transmitter). This operating data and the data for remote maintenance is input via the keyboard of a personal computer (PC desktop or laptop) by authorized operating personnel of the respective operator (usually air traffic control authorities).  System control can be ensured via the PC with the same software both in local mode in direct connection to the system and in remote mode via a modem link. Depending on the selected modem, the data can be transmitted via a switched line or a dedicated line. If a switched line is used the subsystem is automatically selected by the remote station if the selection on the PC has been made accordingly.  Status information of the subsystem is represented on the PC screen in an easily interpretable form. Via a printer connected to the PC system data can be printed out and thus documented.

It is however, possible to select two transmissions rates values: ranging from 800 to 4800 ppps or ranging from 2700 to 4800 ppps.  The difference is given by the minimum number of pulse pairs per second (800 ±50 ppps or 2700 ±90 ppps) transmitted by the equipment. Even in case of no interrogations from the airborne interrogators; as a result, the power consumption will be different. 4.4.7 Reply Delay The reply delay may be defined as the reply interval between an interrogation, in antenna, and the corresponding reply at the same point. On a DME/N beacon, the reply delay may be selected in 0.05 µs steps, as follows: -  from 35 µs to 75 µs for X channels; -  from 50 µs to 75 µs for Y channels. As far as reply delay accuracy according to interrogation level is concerned:  Interrogation  level  delay variation (average)  distance accuracy (average typical) from –10 dBm to –79 dBm  ± 0,2 µs  ± 30 m from –79 dBm to –89 dBm  ± 0,4 µs  ±60 m from –89 dBm to –91 dBm  ± 0,6 µs  ±90 m  4.4.8  Automatic Stabilization of the Reply Delay The reply delay can be automatically adjusted according to the measurements performed by the monitors and of specific circuits on the transponder (circuits of pilot pulse) that they measure and they adjourn the precision of the reply delay in continuity with step of 12,5ns. The average value of the measurements from both monitors is used to modify the reply delay presetting in steps of 12,5 ns. The automatic reply delay stabilization will continue even if one of monitors is faulty, if the monitoring logic set will permitted.

D, September 2005 4.4.9 Reliability In the calculation of the beacon reliability, all alarms of the monitors have been considered primary and the monitors in "parallel" configuration. So that both monitors must detect an alarm at the same time in order to trigger a changeover or a beacon shutdown. The failure rate of the various modules has been calculated in relation to the to MIL-HDBK-217E in Ground Fixed conditions at an ambient temperature of 20 °C and of 55 °C. The following values have been calculated:  MTBF at 20 °C  at 55 °C DME 415, dual station:  over 18.000 hrs  over 11.000 hrs DME 435, dual station:  over 16.000 hrs  over 10.000 hrs DME 415, single station:  over 9.500 hrs  over 6.000 hrs DME 435, single station:  over 8.500 hrs  over 5.500 hrs    4.5 EQUIPMENT DATA 4.5.1 TRANSMITTED signal The stability of the transponder radio frequency signal output is better than 0.001 % apart from the nominal channel frequency. 4.5.1.1 Pulse shape The characteristics of each pulse transmitted are given below: -  rise time: 2.5 µs with a tolerance ranging between –1 µs and +0.5 µs, measured between the points where the amplitude corresponds to 10% and 90% of the peak value; -  duration: 3.5 µs with a tolerance ranging between ±0.5 µs, measured between the points where the amplitude corresponds to 50% of the peak value; -  decay time: never longer than 3.5 µs measured between the points where the amplitude corresponds to 10% and 90% of the peak value; -  pulse top: between the points on the leading and trailing edges of the pulse at which the amplitude is 95% of the maximum, the instantaneous amplitude does not fall below 95% of the maximum voltage amplitude.  4.5.1.2  RF Pulse Signal Spectrum The pulse spectrum of the modulated signal is such, that during the pulse the output power, contained in a 0.5 MHz band centered to ±0.8 MHz with respect to the nominal channel frequency. It is not greater than 20 mW, while in the same band, centered to ±2 MHz, it is not greater than 0.2 mW.  Any lobe of the spectrum is of lower amplitude than the adjacent lobe, which is closer to the nominal channel frequency. The power in the frequency bands is the energy that the frequency band contains, divided by the time of pulse transmission. The time of pulse transmission is the interval, measured between the points on the rise and decay edges of the pulse envelope, at 5% of the maximum voltage amplitude

D. 4-5 4.5.1.3  Out of Band Spurious Output The spurious output is below -40 dBm/kHz at all frequencies between 10 and 1800 MHz, with the exception of the frequency band between 960 and 1215 MHz. 4.5.1.4  In-Band Spurious Output The RF output level in the interval between transmission of pulse pairs is at least 80 dB lower than the maximum power level during the pulses. In addition, between the pulses of each pair, there is an interval of at least 1.0 µs during which the RF output level and is at least 80 dB lower than the maximum power level of each pulse. Finally, the CW output signal does never exceed 5 mW. 4.5.1.5 Harmonics The output power of CW harmonics of the carrier frequency does not exceed -10 dBm. In addition, the peak of any harmonic of the carrier does not exceed +20 dBm. 4.5.1.6 Peak Power Output The transponder output power at the peak of each pulse is not less than 100 Wp for DME 415 and not less than 1kWp for DME 435. It is possible to reduce this power value to 50 Wp ± 1dB (DME 415) and to about 500 Wp ± 1dB (DME 435), programmable a step of 1dB. 4.5.1.7 Transmitted Pulses Only pulse pairs are transmitted. Each transmitted pulse pair is coded accordingly to the operation channel. The difference between the peak power levels of the pulses of any pulse pair does not exceed 1 dB. The difference between the peak power levels of the pulses of each pulse pair (squitter or reply) does not exceed 1 dB. 4.5.1.8  Replies to Valid Interrogations Replies to valid interrogations have a nominal reply delay for the operating channel, as indicated in table 4.1.  Any differences from the nominal reply delay do not exceed the following values: -  ±0.2 µs BIAS and ±0.2 µs NOISE, on a basis of 95 % for interrogations having any level between -5 and -81 dBm. -  ±0.4 µs BIAS and ±1 µs NOISE for interrogations having levels between -81 and   -91 dBm.  4.5.1.9  Identification Using Morse Code The identity signal (ID) consists of pulse pairs transmitted at a constant rate of 1350 (±0.2 %) per second during the key down time express in code Morse international  The characteristics of the identity code transmission rate for the DME transponder are as described below.  The dots have duration of 100...160 ms with a tolerance of ±5 %.  The dashes have duration of three dots.  The interval between the dots and/or the dashes of a character has duration equal to one dot.  The interval between two consecutive characters is not less than three dots.  The maximum duration for the identity code is equal to 64 dots.  The code repetition rate is at least once every 40 s.  The manipulation time with "key down" does not exceed 4 s for each identity group.
955 900 031 C   DME 415/435 -Technical Manual Vol. 1-Section 4 - Technical Spec. 4-6  THALES Italia S.p.A.- A. S. D. Vers. D, September 2005 4.5.1.10  Squitter Output Pulses The squitter pulse pairs are automatically generated and controlled to maintain a transponder minimum transmission rate (replies and squitters) equal to 800 (±50) pulse pairs per second (or 2700±90 pps in case of pulse transmission ranging from 2700 to 4800 pps). These pulse pairs are randomly spaced, but their spacing is never less than 200 µs and there is no spacing in the range from 730 to 750 µs (typical spacing of the identity code). When the transmission rate is greater than 800 pairs per second (or 2700 pps in the other case), no squitters are added. 4.5.1.11 Transmission Priority The transmission of the output signals from the transponder has the following order of priority: -  Identity pulse pairs -  Reply pulse pairs -  Squitter pulse pairs Transmission priority is established in the following way: -  The identity code inhibits the replies and the squitters as long as the dots and dashes last. -  The decoded pulses inhibit the squitter pulses at the encoder input until the reply is transmitted.  4.5.2  RECEIVER AND PROCESSOR CHARACTERISTICS The transponder provides the required performance in response to interrogations from the airborne equipment. The interrogating signals comply with the standards laid down in the ICAO Annex 10 and EUROCAE MPS. 4.5.2.1 Receiver Sensitivity When there is no overload, the DME 415 / 435 transponder's sensitivity is typical better than -91 dBm (can be preset between -76 and -94 dBm via PC keyboard).  The reply efficiency is better than 70%. Under these conditions, the transponder internal noise does not radiate more than 10 reply transmissions per second. 4.5.2.2  Receiver Dynamic Range Accuracy is maintained for interrogating signals having levels between receiver sensitivity threshold selectable values and -5 dBm. The reply efficiency is at least equal to 95%, for a single interrogator with signal levels of at least 10 dB or more greater than the receiver sensitivity threshold. 4.5.2.3  Sensitivity Variation with Pulse Coding If the interrogation pulse spacing differs from the nominal spacing value by ±1.0 µs, and there are no further interrogations, the receiver sensitivity threshold does not decrease by more than 1 dB. Interrogations with a spacing that differs by more than ±2.0 µs and an interrogating level up to a maximum of -10 dBm are rejected. Single pulse is not decoded.  4.5.2.4  Sensitivity Variation with Frequency If there are no other interrogations, the nominal sensitivity threshold value does not decrease by more than 1 dB, when the interrogating signal frequency differs from the nominal value of the operating frequency set by ± 200 kHz.
DME 415/435 -Technical Manual  Vol. 1-Section 4 - Technical Spec.   955 900 031 C Vers. D, September 2005 THALES Italia S.p.A.- A. S. D. 4-7 4.5.2.5  Sensitivity Variation with the Interrogation Load With the echo suppression disabled, and with a decoding dead time of 60 µs, the nominal receiver sensitivity will not decrease by more than 1 dB, when the number of replies has any value up to a maximum of 3600 pulse pairs per second. 4.5.2.6  Sensitivity Variation due to Interrogations on the Adjacent Channel The transponder sensitivity threshold increases by no more than 1 dB in presence of interrogating signals on the adjacent channel at frequencies of ±900 kHz or more far from the on-channel interrogation frequency and correctly coded (for the channel in use), at any level up to -10 dBm and at any interrogation rate up to 3600 pairs per second. The transponder does not reply to interrogations on adjacent channels. 4.5.2.7 Recovery Time The receiver sensitivity will not be reduced by more than 1 dB, when the valid interrogation pairs are preceded by a single undesired pulse which occurs 8 µs or more before the valid interrogation. The period between a single undesired pulse and the valid interrogation pair is measured between the 50% points of the rising edge peak value of the single pulse and the first pulse of the interrogating pair. The single undesired pulse may have all amplitudes up to a maximum of 60 dB above the receiver sensitivity set. The above is valid when no echo suppression device is activated. 4.5.2.8  Continuous Wave (CW) Signal Interference A continuous wave interfering signal on the assigned channel frequency or at any other frequency within the receiver pass band, with peak power of -100 dBm at the receiver input, does not preclude compliance to specifications or modify the reply efficiency to interrogations from the value obtained without CW interference. 4.5.2.9 Spurious Suppression The signal received at the intermediate frequency (63 MHz) is suppressed by at least 80 dB. Any other spurious reply or signal in the band between 960 and 1215 MHz and image frequencies are suppressed by at least 75 dB. 4.5.2.10  Decoding Dead Time The decoding of each valid pair of interrogation pulses generates a dead time interval during which the decoder output is disabled, and therefore any subsequent valid interrogations will not be processed and transmitted, even though they are decoded. The duration of the dead time interval, which is normally set at 60 µs, can be selected from the range of values 50 to 150 µs, at 1 µs steps. 4.5.2.11 Echo Suppression •  Short Echo Suppression Echo pulses which, occur between the pulses of a valid interrogation pair, will not affect the reply timing by more than 0.15 µs. In addition, the reply efficiency will not be reduced by more than 10% with respect to the value obtained, when there are no echo pulses.  This occurs for an interrogating signal with a level between -10 dBm and 10 dB beyond the sensitivity threshold set for the receiver, and for an echo level up to 3 dB lower than the direct signal level.  •  Long Echo Suppression The long echo suppressing circuits are used to suppress the echo pulses, which fall after the dead time interval.
955 900 031 C   DME 415/435 -Technical Manual Vol. 1-Section 4 - Technical Spec. 4-8  THALES Italia S.p.A.- A. S. D. Vers. D, September 2005 These circuits are activated after the decoding of a valid interrogation with an interrogating level, which exceeds the activation threshold of the long echo suppression circuits. The threshold can be selected from the values between 0 dBm (deactivated echo suppression circuits) and -60 dBm. The threshold used for long echo suppression has a level, which is 3 (±3) dB above the interrogating signal level which activated the echo suppression circuits. It has a duration, which can be selected from the values between 50 and 300 µs. 4.5.2.12 Receiver Bandwidth The bandwidth at the 12 dB and 60 dB points do not exceed 2 MHz and 12 MHz respectively. 4.5.2.13 Interrogation Overload The maximum transponder transmission rate is 4800 (±150) pulse pairs per second. When overload occurs, the sensitivity of the receiver is automatically reduced to limit the transmission rate of the transponder. The range of sensitivity reduction is 50dB.  The transmission rate is automatically controlled by simple preventing further replies. The transponder components are additionally protected if transmission should exceed the maximum rate in case of malfunctioning. 4.5.2.14  Receiver Inhibition during Transmission During transmission the receiver is inhibited for a period of time that will not exceed 10 µs for each pulse transmitted.   4.6 MONITORING SYSTEM 4.6.1 General The typical monitoring system consists of two independent monitors, controlled by µP and managed by suitable program.  the two monitors have primarily the function to take measurements whose results, provided to the system of control, make it possible to check the services of the equipment and emitted signal RF.  To take various measurements one uses pulses produced by the interrogators having the same characteristics as the signal coming from RF interrogator of the airborne. The monitors basically perform the following measurements in order to check that the beacon is operating correctly: a)   Executive monitoring; tests continuously carried out on the transponder output signal. b)   Monitor self-check; additional tests carried out together with the executive monitoring to ensure the monitor integrity. c)   Routine checks; pre-established tests of the most important parameters of the transponder and of the monitor itself that can be performed during the normal operation of the beacon; they can be repeated periodically or when requested by the operator. d)   Manual tests; tests specific for maintenance operations; to perform quantitative measurements on the relevant parameters while keeping the beacon in normal operation: the operator may select the type of test. e)   Diagnostics; tests performed in sequence and when requested by the operator, useful to determine the efficiency of the monitor itself and of the transponder connected to the dummy load.

D. 4-9 4.6.2 Executive Monitoring This monitoring action, check the output signal of the transponder(s) and generates a condition of alarm as specified in this section when the predetermined limits are exceeded.  It is continuously carried out for the main transponder connected to the antenna; it can also be carried out contemporary both for the transponder on antenna and for the transponder on dummy load if the standby mode selected is "hot". The operator is supplied with the values of the controlled parameter measurements obtained by both monitors. These values are continuously updated. The tests are performed in approx. 1 s; after a pre-defined delay an out of tolerance parameter generates an alarm condition and as a result the transponders will be changed over or the equipment will be shutdown. See details on the measurements in the table 4.2. It is possible to select a AND or OR monitor logic. - In case of OR monitor logics, both monitors must work correctly to make beacon operation possible. An alarm condition will occur (beacon shut down) when one monitor detect an out of tolerance condition of one parameter. -  In case of AND monitor logics, the beacon will keep working even if one of the two monitors is faulty. An alarm condition will occur when both monitors detect an out of tolerance condition of one parameter (AND logic=best reliability condition default preset). 4.6.2.1  Executive Monitoring Terms • A primary alarm starts an automatic sequence of events to inhibit signal transmission and consequently, restore correct operation by inserting the reserve equipment, if present. • A secondary alarm starts an automatic sequence of events to provide the proper signaling and engage the spare transponder if this can provide a better service. A secondary alarm does not inhibit signal transmission. The measuring period is the interval necessary for acquiring samples of a parameter. • The average value of a parameter is calculated in the measuring period. • The reaction time (time monitors alarms delay) is the interval between an out of tolerance condition occurring and the changeover or shutdown of the transponder by the controller. The reaction time takes the monitor and equipment delays into account. 4.6.2.2  Monitor Insertion Delay The monitors are inhibited for approx. 5 s after the "equipment on" command. 4.6.2.3  Monitor Response to Alarms After primary or secondary alarms the following operations are performed: •  The transponders are switched or powered off. •  A visual and acoustic alarm is emitted at both the local and remote sites. •  The cause of the alarm is identified (monitor parameter), and the value at the time of alarm is stored.  Switching a Single Transponder If there is no standby equipment available, the single equipment is deactivated only when the monitors detect a primary parameter, which is outside of the specified limits. A primary alarm completely interrupts transmission from the station within the given reaction time.  Switching Dual Equipment When there is a standby equipment available, switching guarantee that service continues with the best available hardware, including the secondary alarm conditions. A secondary alarm on the operating transponder causes the equipment to be switched only if the standby transponder's conditions are perfect.  Standby Mode The standby mode of the transponder connected to the dummy load can be set to: -  Normal : Transmitter is off.  -  Hot  : Transponder is operating.

Note 3: The number of interrogations generated by the monitor system does not exceed 120 per second.  4.6.3 Monitor Self-check Each monitor is kept under constant control to check its operation in order to avoid false alarm detection. This is done by performing suitable tests, which are repeated every second. If the monitor fails to pass all tests, it is declared faulty and deactivated within 1 s.  The following tests are performed: • Frequency synthesizer • Interrogator  • IF detector •  AD and DA converters • Timers and counters • Morse Code detector •  Digital circuits (µP, RAM, Eprom).

DME 415/435 -Technical Manual Vol. 1-Section 5 - Maintenance    955 900 031 C Vers. D, September 2005  THALES Italia S.p.A.- A. S. D. 5-1 SECTION 5     MAINTENANCE and TROUBLESHOOTING 5.1 GENERAL  This section contains all data required for maintenance of the Model DME 415/435 - Distance-Measuring Equipment - ground beacons.  This section provides standards and tolerances, maintenance requirements, required test equipment, performance check procedures, information supporting flight check of the station, alignment and adjustment procedures, fault isolation, module replacement procedures, and technical performance records for the DME ground station. Maintenance on the DME beacons is made easier by using a personal computer (PC) based control and monitoring system. This allows the operator to measure and control the main parameters of the DME transponder using the PC keyboard and display.  This beacon does not require any particular maintenance operation. It has been conceived, from a mechanical (plug-in system) as well as from an electrical point of view (use of mainly integrated, solid state components) paying the greatest attention to the reliability factor. This intrinsic reliability is further enhanced by the quality control method as per AQAP-1 requirements, as regards to production cycles, structure and inspection; additionally, all automatically tested modules undergo "burn-in" procedures.  The DME 415/435 has been designed to minimize maintenance requirements using built-in computer controlled test equipment and digital design techniques.  Remote access to the equipment through the modem interface allows the built-in test equipment (BITE) to be used to assure proper DME operation without the need to visit the site.  The faulty modules may be detected following the information given in paragraph 5.3.  Remove and replace time is minimized by the use of plug-in assemblies that are easily accessed from the front of the cabinet. Troubleshooting is made easier by the executive monitoring and test procedures, which perform real-time  Usually, operator, at the local site, does not control the beacon, although its operating conditions may be checked through the messages displayed on the remote PC. The operator may also detect possible parameter variations by displaying the information concerning the automatic monitoring cycle (EXECUTIVE MONITORING), by performing the Routine Check, or by standard or specific measurements in manual tests (Maintenance mode). Then comparing the results obtained to the previous data.  Faster on-site troubleshooting is possible using light-emitting diodes (LEDs) located on the modules.  These make it possible to detect a module failure by looking for an illuminated red LED on any card in the DME card-cage.  Another important instrument for troubleshooting is the DIAGNOSTIC function, which displays the name of the faulty module.  The diagnostic function is described in paragraph D.3.4.4 ANNEX D. There are a few activities of normal maintenance, which should be performed in DME 415/435. All the main parameters are maintained at the preset values throughout the entire life of the system by means of specific circuits and a microprocessor controlled transponder, so that drift as a result of aging, will not occur. No parts that are subject to mechanical wear are used. Since, the periodic maintenance intervals can be made only whenever necessary and the number of measurements restricted to a minimum. In addition, the radiated signals are checked by high-precision microprocessor controlled monitors. These prevent faulty signals from being emitted by either switching over to the standby transmitter or shutting down the system completely. Each monitor is a complete programmable DME instrumentation set in itself (BITE - Built In Test Equipment), capable to perform all tests and checks required for routine maintenance and for automatic diagnostics.  Preventive maintenance activities should be reduced in accordance with local regulations as actual data proves that the requirements in ICAO 8071 are overly conservative. Skilled operators and technicians may perform more, accurate measurements using external instruments. The details about any of these measurements are given in the following paragraphs

Documentation is recorded by the printer connected to the PC or in a file on the PC (the Routine Check is the typical file used). The data recorded during the commissioning and flight check should be recorded and stored in a reference file.  The same procedure should be followed when performing further checks, so the data recorded can be compared with the original flight check data.
DME 415/435 -Technical Manual Vol. 1-Section 5 - Maintenance    955 900 031 C Vers. D, September 2005  THALES Italia S.p.A.- A. S. D. 5-3 5.2 MAINTENANCE 5.2.1 Periodic MAINTENANCE The procedure is performed using the monitors BITE as measurement instruments. Each parameter of the transponder in antenna is measured in real time by the monitor(s), which incorporate a full measuring devices (BITE = Built In Test Equipment). These instruments are constantly verified by its own self-check (integrity check of monitor) and the possible failure will be visualized through proper failure messages and the faulty monitor will be switched off.  The frequency of this test might be reduced according to operator's requirements, to environmental conditions and to the practical experience collected over time. Several customers suggest a periodicity of once every two years.  Every parameter to be measured is associated with the corresponding limits according to Annex 10, Doc. 8071 Part III DME ICAO specifications, the standards and tolerances in para. 5.1.1, and manufacturer's in technical specification data (section 4). The BITEs are performed using a local or remote PC.  General information is given in the following paragraphs: −  the parameters measured with the EXECUTIVE MONITORING and ROUTINE CHECK programs may also be measured using the CHECKS menu; −  in addition to the standard tests, the skilled operator may use the PRESETTABLE tests (ANCILLARY - see ANNEX D section) to create special tests, not provided by the system, necessary to perform particular checks  −  before starting every ordinary maintenance procedure, it is necessary to analyze any possible alarm or warning condition which may have occurred from the last maintenance intervention so as to perform more accurate controls on the parameters showing signs of degradation; −  at the end of the maintenance procedures, print the last Routine Check and the data relating to every measurement performed; compare them to the previous data and to the data obtained upon installation.  −  these controls must be performed on both transponders and it is advisable to perform a final control on the two of them using the diagnostic function (DIAGNOSTIC TEST). Therefore, the equipment does not require typical scheduled maintenance. Only ordinary cleaning maintenance is suggested. For shelter, air conditioner and emergency battery (if applicable), observe, the manufacturers maintenance recommendations. Battery type suggested: low maintenance or sealed type. Additional external measurements are documented in paragraph 5.2.5.  These allow the operator to test the validity of the measuring devices inside the monitor by means of external instruments.  These procedures may be used at the discretion of the maintenance technician.   5.2.2 Routine Tests Routine tests will verify the proper performance of the DME transponder and monitor. This performance test should be run at discretion of operator. All limits should conform to the tolerances in table 5-1 or those dictated by local regulations.  All tests must pass.   If any tests fail, repeat the tests two or three times to verify the failure; then refer to paragraph 5.3 for troubleshooting assistance. a.  For this procedure, data will be printed or saved to disk.  If a printer is to be used it must be connected.  If the data is to be saved to a disk, use the save to a file option that is available when the printer screen appears.

These procedures should be performed to observing the periodic maintenance of the manufacturers recommendations.  Batteries, generate an explosive gas under normal operating conditions if is not used the sealed type.  Special care should be taken to avoid creating sparks that could ignite this gas.   Ensure no tools or other metal objects can fall onto the batteries or otherwise contact the batteries and cause a short.   Batteries contain a very corrosive electrolyte that can cause serious injury to the skin and eyes.   Wear proper protective clothing and eye, hand, and face protection when working with the batteries. a.  Visually inspect each battery and verify it is free of any bulges, cracks, or other deformations.  Replace any defective batteries. b.  Check all battery terminal connections and verify they are tight and free of corrosion. c.  Check that batteries are clean and free of corrosion.  If necessary, remove dust or dirt by wiping with a water moistened cloth.  If battery electrolyte is present on the outer surfaces of the batteries, neutralize it with a solution made up of 1/2-pound baking soda in 1 quart of water (0.22-kilograms soda/liter water).  Initially, this solution will bubble.  The electrolyte is neutralized when bubbling no longer occurs when fresh solution is applied.  When electrolyte is neutralized, wipe battery clean with a water moistened cloth.  Dry battery with a dry clean cloth. d.  Using a digital multimeter or equivalent, measure voltage across all batteries.  This voltage should be approximately 54 volts DC.  Record this voltage. e.  Divide the voltage recorded in step "d." by 4 and record this voltage. f.  Measure and record voltage across each battery.  The voltage across each battery should be the voltage recorded in step "e" ± 0.2 volt DC. g.  Turn off the AC power and record the time. h.  Five minutes after performing step "g", measure and record voltage across battery supply. i.  Twenty minutes after performing step "g", measure and record voltage across battery supply. This voltage should be no less than 0.2 volt DC less than the voltage recorded in step "h".  If battery supply fails this check, measure and record voltage across each battery.  If voltage across one battery is 0.5 volt DC or more below voltage recorded in step "e", replace that battery.  Charge the battery and repeat steps "d" through "i".  If the voltage across two or more batteries is 0.5 volt DC or more below voltage recorded in step "e", charge battery supply and repeat steps "d" through "i". j.  Turn on the AC power.  WARNING

Clean the inside and outside of the equipment cabinet when become necessary. Avoid transferring dirt on DME cabinet during the cleaning: use always a vacuum cleaner.      Cleaning aids, such as brushes and dusters, must be made of anti-static material.  Use only a soft cloth; do not use corrosive and abrasive substances. The local control and status unit (LCSU) front panel, may be damaged by some types of chemicals used for cleaning.  To remove layers of dirt on the LCSU panel, use ethyl alcohol, glycol, or clean water.  Moisten a cloth with one of the liquids mentioned above and remove dirt.  Dusting of the subassemblies should only take place in conjunction with removal of a subassembly when this becomes necessary. Even then, subassemblies should only be dusted if dust can be detected by means of a visual check. They should always be dusted using a soft brush, and if possible with the aid of a vacuum cleaner. During such operations, it is essential to observe all precautionary measures for voltage-sensitive semiconductors.  5.2.4.2 Other checks •  Inspect all components to ensure that there is no damage, corrosion, or evidence of overheating. •  Verify that all components are securely mounted. •  Verify that all electrical connections are secure.  5.2.4.3  Antenna Installation inspection  Inspect complete antenna mast installation, coax and connectors of antenna cables, line and obstruction lights for any damage caused by corrosion, rodents, termites, or others.

The operator can also measure the system reply delay.  The procedure uses a dual channel oscilloscope.  This method is not as accurate as the technique used in the monitor.  The results obtained using the scope will typically be with ±5 percent of the readings displayed by the monitor. Oscilloscope connections: • Channel one is connected to monitor test point AN34.  See figure 5.23 • Channel two is connected to transmitter test point AN7 (TX100-DME 415) or "AN 7 RF detected" (TKW - DME 435).  See figure: 5.30 (DME 415), 5.33 (DME 435) • The external trigger input of the oscilloscope is connected to monitor test point AN2 (or AN72).  See figure 5.16. • Adjust the time base and trigger to allow the interrogations on channel one and the replies on channel two to be displayed on the screen. a.  Rise Time.  Examine the pulses on channel two of the oscilloscope.  Set the oscilloscope time base to 1 or 2 μs.  To measure the rise time, measure the time for the leading edge of the pulse to transition from 10 percent of its peak value to 90 percent of its peak value.  Record this time. b.  Duration.  Examine the pulses on channel two of the oscilloscope.  Set the oscilloscope time base to 1 or 2 μs.  To measure the duration, measure the time between the 50 percent point of a pulse rise time and the 50 percent point of the pulse fall time.  Record this time.

Examine the pulses on channel two of the oscilloscope.  Set the oscilloscope time base to 1 or 2 μs.  To measure the fall time, measure the time for the trailing edge of the pulse to transition from 90 percent of its peak value to 10 percent of its peak value.  Record this time. d.  Pulse Spacing.  Examine a pulse pair on channel two of the oscilloscope.  To measure accurately the pulse spacing, measure the time between the 50 percent point of the pulse rise time of the first pulse and the 50 percent point of the pulse rise time of the second pulse.  Record this time. e.  Verify that the values read on the scope are equal (± 2 percent) to the values measured by monitors (on test of executive monitoring or routine check). f.  Reply Delay.  Channel one shows the interrogation pulses.  Channel 2 shows the transmitter pulses.  Set the oscilloscope time base to 10 μs.  Measure, accurately, the time from the 50 percent point of the leading edge of the first constituent pulse of the first pulse pair on channel one, to the 50 percent point of the leading edge of the first constituent pulse of the first pulse pair on channel two. Other method of measure, of the replay delay, is that shown in figure 5.19. g.  Verify that the values read on scope are equal (± 1 percent) to the values measured by monitors (on test of executive monitoring or routine check).  5.2.5.4 Transponder Frequency Measurement This procedure measures the DME transponder frequency.  The frequency source used by the transmitter and receiver is located in the receiver module.   a.  Connect PC to DME front panel RS-232 connector. b.  Log on.  Use Commands to turn beacon one off. c.  Remove the low-power transmitter module (TX).  The module may be removed with power on. d.  Connect frequency counter to the upper RF connector that interfaces with the removed transmitter assembly.  Use the BNC female to backplane female adapter to convert the top connector to a BNC female connector.  This will allow a cable with BNC male connectors on both ends to be used with the frequency counter. e.  Frequency counter should indicate station assigned carrier frequency ±0.001 percent. f.  Disconnect adapter, cable, and frequency counter. g. Replace transmitter. h.  For a dual system, use Commands to turn beacon two off.  Repeat steps c through g with the second transmitter. i.  Replace the transmitter(s).  Restore the system to normal operation. j. Log off.   5.2.5.5 Pulse Spectrum NOTE This procedure is significant for sites where beacons or other radio equipment are installed within a radius of 5 NM (Nautical Miles) and have adjacent channel frequencies. Therefore, it is not necessary if these conditions are not present.
DME 415/435 -Technical Manual Vol. 1-Section 5 - Maintenance    955 900 031 C Vers. D, September 2005  THALES Italia S.p.A.- A. S. D. 5-11 Procedure: a.  Using a 40 dB attenuator for DME 435 and 30 dB for DME 415, connect the spectrum analyzer to the coaxial cable, coming from one of the two antenna probes. First, disconnect the cable from its connector on top of the equipment cabinet. b. Use a 30 to 100 kHz/div band width and select the beacon frequency for the spectrum analyzer. Position the spectrum lines on the raster center of the instrument display and adjust the signal peak level so that it touches the first top line of the raster. c. Verify that with FREQUENCY SPAN equal to 0.5 MHz/div, all the spectrum lines at a frequency greater than the beacon frequency ±2 MHz are attenuated of at least 65 dB for DME 435 and 58 dB for DME 415 with respect to the beacon frequency peak level, at raster center. d. Verify that with FREQUENCY SPAN equal to 0.2 MHz/div, all the spectrum lines at a frequency greater than the beacon frequency ±0.8 MHz are attenuated of at least 47 dB for DME 435 and 40 dB for DME 415 with respect to the beacon frequency peak level, at raster center. e.  At the end of the measurements, take note of the values concerning both transponders and restore the initial connections.   5.2.5.6 Transmission rate  a)  Perform the executive monitoring cycle and/or the Routine Check and/or TRANSMISSION RATE manual test. b)  Verify that the obtained value comes within the limits indicated. c)  Connect the frequency counter to AN7 test points of transmitter TX module. See figure 5.30. d)  Set the counter to read the frequency values in the low frequency range (<100 kHz and high input impedance) and to count the pulses.  Because of the random nature of DME output pulses, the frequency counter will not display a constant value.  The reading will be affected by aircraft interrogations.  Do not use a value measured during a DME identification period.  The counter reading will increase during the DME identification period.  Divide the frequency counter reading by two to obtain the frequency of pulse pairs (as read by the monitor). e)  Read the value given by the instrument and verify the reading (divided by two) is within the indicated tolerance limits. NOTE The actual ppps number depends on the transmission rate selected and on the number of interrogating aircraft at the instant the measurement is made.  5.2.5.7  Monitor Interrogation - Pulse shape, pulse spacing and peak pulse level The external trigger input of the oscilloscope is connected to monitor test point AN2.  See figure 5.16 Connect the probes of oscilloscope on test point AN34 "Out MUX" of the MON module and record:  − Rise time − Duration − Decay time − Pulse spacing −  Peak pulse level Verify that the values read on scope are equal (± 2%) to the values measured by monitors (on test of executive monitoring or routine check)

D, September 2005 5.2.5.8 Power Supply Measurements This test measures the key power supply voltages in the 415 DME. a.  Measure the +5 volt (nominal value: 5,1V), +15 volt, and –15 volt levels using the test points on the PWS module.  See figure 5.17 for the test points location.  See table 5-1 for tolerances.  For a dual system, perform measurement on both PWS modules. b.  Measure the AC input voltage.  The voltage should be measured at the terminal where AC power comes into the cabinet.  Dangerous voltage (240 V AC) exists within the DME system (only on subrack BCPS unit). Contact with this voltage can cause personnel injury or death.  c.  Measure the DC bus voltage.  This can be done at the top, left (front) corner of each transponder card cage backplane.  This point is labeled +48.  The point to be measured has a red wire.  Chassis ground can be used as a reference.   The DC bus voltage can also be measured using the + and – test points on the AC/DC module.  See figure 5.35. d.  Measure the output of the DC/DC converter on the low-power transmitter module (TX).  See figure 5.30 (AN 17) for the test point location.  See table 5-1 for tolerances.  For a dual system, perform measurement on both TX modules. e.  Measure the output of the DC/DC converter on the 1000 watt transmitter module (TKW). See figure 5.33 (AN 1 DC/DC Out) for the test point location.  See table 5-1 for tolerances.  For a dual system, perform measurement on both TKW modules.   5.2.5.9  Verification with Diagnostic Function The Diagnostic is the last operation to be performed and is used to check both transponders. If this verification and previous inspections and controls confirm the good beacon operating conditions, all beacon mechanical and electrical components as well as its software can operate correctly. With regard to the software, it should be noticed that most of its functions have been enabled during the measurements. To run the Diagnostic software, place the DME in maintenance.  Select the Diagnostic test from the Checks menu.  See Annex D for more information.    5.3   TROUBLESHOOTING  This paragraph contains only the information necessary to detect and replace faulty modules, which should then be repaired at an authorized repair facility. Troubleshooting is made easier thanks to the built-in testing available in the 415/435 DME. By looking at the failure messages displayed on the PC video, the operator may easily detect any beacon malfunction; these messages make it possible to detect the malfunctioning module, if any, and to take the necessary organization and urgency measures (primary or secondary alarm) so as to repair the module at the local site. Considering the functional services offered by the beacon, when both transponders are shut down, it is advisable to first restore one of the two transponders using the redundant and operating modules of the other one. WARNING
DME 415/435 -Technical Manual Vol. 1-Section 5 - Maintenance    955 900 031 C Vers. D, September 2005  THALES Italia S.p.A.- A. S. D. 5-13 The technicians involved in troubleshooting should have a good knowledge of 415/435 theory of operation. The technician must be familiar with safety measures required to prevent injury to maintenance personnel and damage to the beacon. Replace the modules in the sequence indicated by the diagnostics; before every replacement, display all possible stored alarms or warnings occurred from the last maintenance intervention. According to the color, the warning lights on the different modules will have the following meanings: −  Green light: normally on, it indicates that the module or circuit being controlled is operating. −  Red light: normally off, it comes on in case of failure of the module. −  Yellow light: normally on, it provides further indications (secondary or partial) about beacon operation. The same color method is used for the messages displayed on the video: these messages may be seen only if a color video is used. The WARNINGS, ALARM, SHUT-DOWN and HARD (primary alarm presence indication) messages are red and flashing so as to be easily seen even on a monochromatic video.  When the beacon is in good operating conditions, no red LED should be on and no red message should appear on the PC video. Before replacing a module with a red LED on, it is advisable to reset the module or the beacon since a transient malfunction might have caused a protection to be activated and therefore the LED to be lit. The reset pushbutton on the DMD or MON modules can not be used if an initialization is being performed.  Connections made with flat and coaxial cables and to passive, non-plug-in components offer a high reliability level; they, however, should not be overlooked, but may be checked in conclusion.  Proceed with great care when it is necessary to work on BCPS unit rear part since a 220 Vac dangerous voltage is present. Radio frequency voltage on RF power amplifier modules output represent a personnel hazard.  Inside AC/DC modules there are the 220 Vac mains voltage and the corresponding 300 Vdc rectified voltage whose capacitors may remain loaded for several seconds after the modules are disconnected. After removing the modules wait for a few minutes before touching the internal circuits.     RF loads (antenna cable, 50 Ω loads) should always be connected when the transponder is set to OPERATING to prevent the RF components from being damaged. 5.3.1  Useful Information for Troubleshooting  The procedures for the remote site are true for the local site as well, but not vice versa. The remote site is a center or a control site situated far away from the place where the beacon is installed. The local site is the place, near the antenna, where the beacon is installed. The two sites may be a few meters or many kilometers apart. Remember that the modules should be replaced when the beacon is off/stby condition.  For repairing operations at local site, the following items are required: −  tool kit and spare fuses, supplied with the beacon; CAUTION WARNING

Since both monitors are used for the tests, these monitors and the power supply modules are checked before all the other modules. Any possible faults are indicated with appropriate error messages displayed on the video of the PC from which the diagnostics has been activated. 5.3.2.1.1  Primary Voltages The local or remote operator may obtain only the information relating to the site, where the equipment is standing. Remember what follows:  The type of power provided to the beacon is clearly indicated on the PC video (POWER:MAINS and POWER:BATT. messages). If the mains power fails the beacon will be switched to battery power supply and its operation will not be interrupted: the POWER:BATT. message will appear on the video. A protracted mains failure may lead to battery depletion and to a resulting interruption of beacon operation. 50 A/h batteries standard autonomy is approx. 8 hours; it is therefore advisable to check the external electrical panel breaker should the mains failure protracts for more than 4 hours. If both mains and battery power supplies fail, the PC video will be in initialization request message by the equipment displayed on the PC video.

D. 5-15 5.3.2.1.2    Stabilized Power Supplies  The operator may obtain only the information relating to the site, local or remote, where he is standing.   Remote Site A faulty AC/DC module in the BCPS unit is indicated by the relevant warning message AC/DC FAULTY, on PC monitor .The POWER:BATT. message may be visualized if there is no power from the mains, or also if both AC/DC modules are faulty.   Before removing the housing of AC/DC module waiting for about 1 minute after shoot-down the supply and removing the line connections   Failure of the PWS, TX, TKW modules is indicated by message of warning and may be visualized the value of regulate voltages.  Local Site A faulty AC/DC module in the BCPS unit may be detected through the green LED on the front of the module. The faulty PWS module may be detected by the corresponding green LED off. In this case, proceed as follows: reset the module by pushing the appropriate pushbutton, check and if necessary replace the module fuse and, if the malfunction can not be eliminated, replace the module.  The correct operation of the TX and TKW (DME435 only) module DC/DC converters is indicated by the corresponding green LEDs, which should be on if the corresponding transponder, is set to OPERATING.  5.3.2.2  I/O System The parts of the I/O system that could result faulty are listed below, starting with the most probable: −  CSB module in the LCSU unit; −  INC module in the LCSU unit; −  I/O panel (connectors on top of the cabinet); −  interconnecting cables and connectors. Diagnostics is essentially based on checking the indications provided by the front panel of INC module. Some of the more common cases are described below. a.  No indication or command possible Probably a power failure: check the voltage (+5V) of CSB module. If the measured value is +5V       ± 5%, the fault is probably on the CSB or INC board, or the connection cable. b.  Green OPERATION indicator in LCSU section switches off. Probable hardware or software fault on CSB board; this condition is also caused by <4.7 V power supplies. c.  Yellow WARNING indicator switches on in LCSU section. A hardware fault in RTC (Real Time Clock) circuit on CSB board. d.  Red DATA COM indicator switches on in MAIN STATUS section. Indicates no communication between LCSU unit and the equipment modules. This condition may be caused by faults in the serial port circuit on CSB board, or the interconnecting cables and connectors.  WARNING
 955 900 031 C   DME 415/435 -Technical ManualVol. 1-Section 5 - Maintenance 5-16 THALES Italia S.p.A.- A. S. D. Vers. D, September 2005 Before replacing the CSB board, make these two tests: a.  Press the LAMP TEST pushbutton located in the LCSU section and verify the indicators are working properly. b.  Shut down all the equipment from the control panel then switches on again after a few seconds. If the fault persists, replace the CSB board since the failure is not caused by a transient fault condition. The INC board can be indirectly tested through the LAMP TEST. By verifying that the individual indicators and buzzers are operating and using the control push-buttons, check they are working efficiently. If the indications and commands are correct on the PC and the corresponding indications are different on the INC module, there may be an INC board fault or the configuration made is not correct. The serial and parallel ports I/O can be checked by verifying the ON/OFF levels using the Hardware Test described in section 3 in this volume; item [3] of the main menu displays the HARDWARE TEST command that can be used to test all the parallel line inputs and outputs and all the serial channels either separately or in groups. Cable or connector faults are unlikely to occur.  When they are present, a visual inspection will often indicate where a cable has been damaged.   5.3.3    Modules Replacement Procedures a) All the modules may be removed and installed without removing power.  The special design of the connector that supplies power to each module prevents damage to the electronics from occurring. b) Modules replacement is made easier thanks to the plug-in technique and to the upper and lower extractors every module.  To extract these modules, lift the extractors (push them towards the inside of the beacon) and pull the module out of its guides. To reconnect the module, reinsert it back in its guides, push it in and lower the extractors. c) Several of the modules have jumper switches on their printed circuit boards. It is essential to check that the switches or jumpers on the new PBA are set to the same positions as on the old module. Section 2 "INSTALLATION" contains the list of the jumpers. d) Modules with extractors do not require any special operations for their replacement, except for the DPX and TKW modules, which requires unscrewing the proper front screws and coax. cables disconnection. e) Outline drawing are shown in this section  f) For other modules, not proved with extractors and requiring particular procedures, proceed as described below.  g) The specific RF connectors plug-in, situate at the back panel and associated to semi-rigid coax cables, must be fixed in sure way from the proper nut, by using the spanner of 16 mm.  They must have little end clearance to help the insertion system.  On each removed module, to check and regulate manually that each RF connector on the back panel are under the previously mentioned conditions. The modules interested at these notes are RX, MON, DPX, TX100 and TKW. Connectors SMA must be fixed with the torque wrench (1Nm/8.9in-lbs) code 870952302X. You have this spanner in the tool bag of the equipment. Connectors "N" of coax cables, must be screwed and blocked in sure way. NOTES: Check that all the RF cables have been connected correctly before switching the transmitter on again, and make sure that either the antenna or a dummy load is connected   On some modules are scheduled opportune trimmers that are factory adjusted: they must not be tampered with, if the maximum precision of system wants to be obtained.  After having replaced the TX100 or/and TKW module it is essential to follow the described procedures to paragraphs 5.3.5 and 5.3.4 for the respective channel of operation

D. 5-19 5.3.3.5.1.1 Battery replacement To back up data in the non-volatile random-access memory (RAM) in case of a voltage drop, the subassemblies LCSU/CSB contain NI_CD batteries. The battery voltage is checked by the BITE of the system. The individual batteries are soldered to the PCB. The battery back up function is enabled via jumpers (M1 of Figure 2.19 section 2)set during first setup or before replacing the respective PCB. Contents of the RAM will be lost when the jumper is opened which enables battery voltage to the RAM device. Always observe the label on the battery. The battery has to be replaced by the same battery type.  The presence of dirt or moisture on the board can increase the battery current consumption and decrease the battery life. It’s also necessary to check that the solder side of the board does not contact the conductive plane, in order to avoid short-circuits or excessive current consumption. If replacement of the battery is necessary, attention must be paid to the correct polarity as well as the electrical characteristics of the new battery (see CSB board layout - component ref.: BAT1). Replace the battery when the voltage is < 3Vdc, reading on proper terminals without the 5V power supply on the card. A soldering iron with a grounded soldering tip should be used.  Remove M1 jumper during the battery replacement Re-tin the soldering tags of the new battery in order to ensure a good soldered connection    Do not recharge, disassemble, heat above 100°C, burn the cell. Do not short-circuit or solder directly on the cell. Violation of the rules regarding the use of rechargeable batteries may cause risk of fire, explosion, toxic liquid and gas to leak out. These batteries must be eliminated with proper precautions. 5.3.3.5.2 INC Module To remove the board, loosen the two screws and six columns on the CSB board. 5.3.3.6 COAX Relay assembly Make sure the transponder is off/stby Loosen the ten screws located on top of cabinet Disconnect the coax cables connectors as follows:  1.

Modify references values for Mod Trx (example)  Procedures for data change: 1)  Modify the parameters (Power Level 100W), (Ped. Mod. Dur.) and (Power Level 50W):  Set in operate status the transponder TRX1 in antenna and to note the power result reading on the "Peak Power Meter " of figure 5.3 2)  Modify the values to obtain the reading of power 100Wp on Peak Power Meter. Click on button OK after the modifications to confirm the changes 3)  So ready, press key "Write EEPROM" (this will write the new parameters on E2prom of the module and will create a file with the extension ".TMP" containing the new parameters). The box, under the key "Write EEPROM", when illuminated, will show the advance of the process in progress. 4)  Reset on module DMD to stored new arrangement (NOTE:  maintain pressed the button of reset during few seconds until to obtain lit red LED) NOTE:. The Software of A.M.C.  ("Automatic Modulation Control ") of DMD module acts as the multiplying coefficient with the reference number for the 10% of the detected peak pulse signal transmitted and changes the pedestal level on modulation signal.  For example:  one pulse pedestal duration approximately of 5.8µs must be reduced from value current 100 (in COUNT) by changing it into 95 (count). In this case, we will have:  (95/100) * 5.8 = 0.95 * 5.8 = 5.51µs.  The 5.51µs will be the new pedestal duration value; the width of pulse (measured at 50% of amplitude) is also proportionally reduced. REMARK:  Whereas is replaced a module TX100 (and/or TKW), it is always necessary to perform the reset hardware on DMD  module with the purpose to align the DMD memory to the EEPROMs data.  The new data of the reference counts are stored in E2PROM, only after having carried out the reset on DMD

The alignment is possible only on site (not by Remote Control) For calibration in the presence of antenna RF cables see section 2 - Installation - and for measurements of Power Reading by the monitors, see procedures described in paragraphs 5.3.7.  TX and TKW modules are equipped with EEPROM serial memory in which are memorized the data used by the software of automatic modulation. This software controls the leveling of the output power, specific channel and mode operating, and the optimization of the pulse shape.  A special software package (EEPROM TX /TKW) is made for EEPROM reading and writing. This software is included in the "equipment manager" program (see section ANNEX D in this volume).   The software (EEPROM TX /TKW) is allowed on following conditions:   1) MAINTENANCE mode (see the section ANNEX D "WINDME400 equipment manager" in this volume)  2)  The two transponders should be in stand by status   3)  Instruments necessary for calibration:   oscilloscope, peak power wattmeter, attenuators, spectrum analyzer  The instrumentation of test set-up for measurements is shown in figure 5.3.  5.3.5.1  DME 435 1KW Program ACTIVATION From "DME400 equipment manager" program in "Maintenance mode" and transponders in stand-by, activate the software "E2prom TX/TKW", pressing, at the same time, the combination keys "CTRL+F10" on keyboard of the PC.

D. 5-29 2)  Modify the values to obtain the reading of power 1000Wp on Peak Power Meter. Click on button OK after the modifications to confirm the changes. 3)  So ready, press key "Write EEPROM" (this will write the new parameters on E2prom of the module and will create a file with the extension ".TMP" containing the new parameters).  The box, under the key "Write EEPROM", when illuminated, will show the advance of the process in progress. 4)  Reset on module DMD to stored new arrangement (NOTE:  maintain pressed the button of reset during few seconds until to obtain lit red LED) NOTE:. The Software of A.M.C.  ("Automatic Modulation Control " of DMD module) acts as the multiplying coefficient with the reference number for the 10% of the detected peak pulse signal transmitted and changes the pedestal level on modulation signal. For example:  one pulse pedestal duration approximately of 5.8µs must be reduced from value current 100 (in COUNT) by changing it into 95 (count). In this case, we will have:  (95/100) * 5.8 = 0.95 * 5.8 = 5.51µs.  The 5.51µs will be the new pedestal duration value; the width of pulse (measured at 50% of amplitude) is also proportionally reduced.  REMARK:  Whereas is replaced a module TX100 (and/or TKW), it is always necessary to perform the reset hardware on DMD  module with the purpose to align the DMD memory to the EEPROMs data.  The new data of the reference counts are stored in E2PROM, only after having carried out the reset on DMD  5.3.5.3  Notation for the calibration of RF output power of the TKW Prepare the instrumentation as of figure 5.3  NOTES:   a) The automatic modulation control (AMC) is obtained by the signal detected at output of the TKW module, which is addressed to the entry of the converter analog/digital of DMD module.   b)  Channel 1 (CH1) of the oscilloscope is joined to detected signal RF on TKW output present on test-point AN36 of DMD module c) Channel 2 (CH2) of the oscilloscope is joined to the signal of modulation V_MOD present on test-point AN13 of TX100 module d) The trigger of external synchronism of the oscilloscope is joined on test-point AN11 of TX100 module Figure 5.7 shows the waveform of the signal detected "V_det" (on test point AN36 DMD) with the main parameters in the conditions of optimal full power. The waveforms have the following definitions:   1) V_det_peak:  Value of the peak voltage detected, offset level excluded.  Value dependent narrowly by the modulation peak level. (Typical value = 10mVolt x Counts in EEPROM:1Vp for 100 counts) 2) 10% width:  Duration of the detected pulse on 10% of peak level (typical 5,8 µs for 100 accounts, 5,1µs for 95 accounts).   3) Offset:  typical level value, approximately 100 mVolt, added in factory adj. on DMD module  5.3.5.4  Calibration of output power RF for TKW 1)  With the equipment connected as figure 5.3 to measure the peak power output by wattmeter.  The typical precision of measurement will be:  ±10% (consists of tolerance of: ±1 count, coupler, attenuators, ….) 2) Modify counts of the parameter "Power Level 1000W" as figure 5.12 for 1000 W reading on the Wattmeter of figure 5.3.  3) Modify counts of the "Ped. Mod. Dur." parameters in order to obtain the pulse shape, similar to the detected signal of figure 5.7 (TP AN36 DMD). Avoid realizing pulses as in figure 5.9.  Comply with the tolerances of the pulse shape defined by ICAO as in table 5-4.   The counts " Ped. Mod. Dur." changes the values of pulse width with 10% of the peak level.   Check with the spectrum analyzer which the spectrum is within the limits of the characteristics marked in figure  5.36b) and, if necessary, to change the " Ped. Mod. Dur." count parameter for to obtain the required results.
