3-1SECTION III PRE-INSTALLATION CHECKOUT 3.1 INTRODUCTION This section describes a functional bench test to be performed before installing and testing the 5200 Series STL Transmitter and Receiver according to the procedures given in Section V. By completing the pre-installation checkout, the user can be certain that the equipment is operating properly. CAUTION Do not connect the transmitter antenna output directly to the receiver antenna input. Doing so will damage the receiver input circuitry. 3.2 PRIMARY POWER APPLICATION Before power is applied to the 5200 Series STL Transmitter, insure that an adequate load is connected to the RF Output Connector. For back-to-back testing, place the transmitter and receiver next to each other. Terminate the transmitter output in a 50 Ohm load of 50 watts or larger rating. To insure that the transmitter and receiver function as a system, we recommend the following checkout procedure before final installation of the system. a. Place the front panel RF POWER ON/STANDBY switch to the STANDBY position. b. Connect the AC power connectors to the correct line voltage. c. The units are now ready for test.
4-1SECTION IV OPERATING THE 5200 SERIES ANALOG STL TRANSMITTERS and RECEIVERS 4.1 INTRODUCTION The 5200 Series of Transmitters and Receivers are conventional composite and mono systems designed to meet today’s stringent broadcasting requirements. Each transmitter or receiver is fully compatible with other TFT systems of comparable configuration. The 5200 series of transmitters is designed to fulfill requirements for composite stereo, composite stereo with MUX, and mono applications. The 5200 series of receivers is available for composite/mono, composite, and mono only configurations. Frequencies from 140 MHz to 2 GHz will be available. 4.2 OVERVIEW OF OPERATION These instructions assume that the units have been configured by the factory and that the Pre-Installation Checkout has been completed in accordance with the instructions in Section III of this User’s Guide. 4.3 SETTING TRANSMITTER PARAMETERS See Section II for details of the transmitter front panel and rear panel connections. Make sure that RF power is turned “off” and that the transmitter is connected to a proper load or antenna. Pressing the center (ENTER) button to the right of the display will advance the LCD through various pages for setup. The default page should have an indication for “FRQ”. Increment the frequency desired for operation with the “UP” and “DOWN” arrow keys until the desired frequency is displayed. Once the desired frequency is displayed, press the center (ENTER) button to “load” the desired frequency into the unit. No further adjustments are required to change frequency. No tuning adjustments are required to change frequency within the range of frequencies at which the unit operates. It will tune the entire band automatically. The screw adjustment to the right of the LCD will increment the output power to the desired level between 0.5 Watt and 20 Watts. The unit is now ready for operation. The RF power “On” switch may be pressed. 4.4 OBSERVING TRANSMITTER OPERATION The center (ENTER) button to the right of the display to advance through display pages to observe various operating parameters, including frequency, power output, reflected power, VCO status, etc. 4.5 SETTING RECEIVER PARAMETERS The receiver operating frequency is set in a fashion similar to that of the transmitter (See Section 4.3 above.). Pressing the center (ENTER) button to the right of the display will advance the LCD through various pages for setup. The default page should have an indication for “FRQ”. Increment the frequency desired for operation with the “UP” and “DOWN” arrow keys until the desired frequency is displayed. Once the desired frequency is displayed, press the center (ENTER) button to “load” the desired frequency into the unit. No further adjustments are required to change frequency. No tuning adjustments are required to change frequency within the range of frequencies at which the unit operates. It will tune the entire band automatically.
4-2After the unit is installed, all operating parameters should be recorded in order to establish a baseline for future maintenance and operation. RSSI (Received Signal Strength Indication) should be noted, along with all VCO and voltage readings. This will assist trouble shooting in the future by having comparison readings.
5-1SECTION V INSTALLATION 5.1 INTRODUCTION This section describes the installation of the Model 5200 Analog STL Transmitter and Receiver Series and their related options and equipment after they have been unpacked and tested according to methods described in Section IV. Electrical ground for the Model 5200 Transmitters and Receivers is established through the AC power cord. Additionally, there is a grounding stud on the rear of each unit. If a more substantial technical ground is available, it may be connected to the chassis box directly at the grounding screw, using a short piece of braid. Proper grounding, good engineering practice, and safety depend on the knowledge and care of the installing engineer. All units are designed to mount in a 19” rack or cabinet using (4) 12-24 pan head machine screws. Mounting requirements: Size: 3.5”H x 19”W x 12”D (8.9 cm x 47.5 cm x 30.5 cm) Maximum. Weight: Approximately 20 pounds (9 kg.) Power requirements: Input power: 117/240 VAC @ 50/60 Hz, 100 Watts maximum, 3 Prong Power Cord - UL style SVT Environmental requirements: 0°C to 50°C (32°F to 122°F). General Hazards: a. Elevated Operating Ambient Temperature - If installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environment may be greater than room ambient. Therefore, consideration should be given to installing the equipment in an environment compatible with the maximum rated ambient temperature. b. Reduced Air Flow - Installation of the equipment in a rack should be such that the amount of airflow required for safe operation of the equipment is not compromised. c. Mechanical Loading - Mounting of the equipment in a rack should be such that a hazardous condition is not achieved due to uneven mechanical loading. d. Circuit Overloading - Consideration should be given to the connection of the equipment to the supply circuit and the effect that overloading of the circuit might have on over-current protection and supply wiring. e. Reliable Earthing - Reliable earthing of rack-mounted equipment should be maintained. Particular attention should be given to supply connections other than direct connections to the branch circuit (e.g., power strip use).
SECTION VI THEORY OF OPERATION 6.1 GENERAL This section describes the theory of operation for the Model 5200 Series STL Transmitter and Receivers. The Model 5200 STL Transmitter accepts either balanced or unbalanced composite or monaural audio on the rear panel. The composite input level should be 3Vp-p for ± 50 kHz deviation. The program input is adjusted by R22 on the Main Board. Similarly, there is an unbalanced input for a MUX channel, the level of which should be 1.2Vp-p for ± 12 kHz deviation. The MUX deviation is adjusted by R29 on the Main Board. J10 sets the transmitter for “Flat” composite or monaural operation. J11 sets the transmitter pre-emphasis to 75 µsec; J12 sets the pre-emphasis to 50 µsec. Only one of these three jumpers should be made at any time. If the optional SCA generator is utilized, then J19 should be connected between pins 2 and 3; if an external SCA generator is utilized, the J19 should be connected between pins 1 and 2. The summed output of the program and SCA networks is routed to a 70 MHz VCO Modulator, which consists of U14 and U13. Linearity of the modulation is adjusted by R64. The 70 MHz modulated VCO output (-18 dBm) is mixed in U27 with a local oscillator (+3 dBm), which operates 70 MHz below the output frequency. This on-frequency, modulated signal (-24 dBm) is filtered by FL2, then amplified by U28, which adds approximately 30 dB of gain. The output of U28 (+3 dBm) is again filtered then amplified by U29, a 15 dB gain amplifier, for a final output from the main board of approximately +15 dBm. The local oscillator consists of a dual Phase-Lock-Loop, which consists of a TCXO that operates at 20 MHz and U20 (VCO1), VCO2 and U21. The frequency is referenced to the 20 MHz TCXO and actually set by U19 and U24, which are controlled by logic programmed by U1. The modulated, on-frequency RF output of the main board is routed to the input of the power amplifier, where the signal is furthered amplified and filtered by U1 and strip-line filters on the Power Amplifier Board. U10, U11, U6A, U8A on the Main Board control lock-out and remote control functions. Metering samples for PGM, MUX, FWD PWR, REV PWR, VCO1 bias, VCO2 bias, and VCO3 bias are furnished to U1 and subsequently scaled and displayed by the front panel LCD. 6.2 MODEL 5200 STL TRANSMITTER BASIC DIAGRAM DESCRIPTION The 5290 Transmitter consists of a Main Board, a Display Board, a Power Amplifier, and a power supply. The Main Board contains input processing and metering, the local oscillator, mixer, and RF output circuits. The Display Board receives display information from the Main Board for display on the front panel LCD. The Power Amplifier amplifies the modulated, on-frequency RF output from the Main Board to the proper RF output level on the rear panel. 6.3 MODEL 5291 STL RECEIVER BASIC DIAGRAM DESCRIPTION (To be supplied) 6-1
SECTION VII MAINTENANCE AND REPAIR 7.1 INTRODUCTION The 5200 Series STL Transmitter and Receiver have no moving parts or components that require routine replacement. They require only minor audio adjustment. 7.2 TOOL AND TEST EQUIPMENT REQUIREMENTS The following tools and equipment are required for analog STL system maintenance: • Hand Tools • RF Spectrum Analyzer, 10 GHz • Digital Voltmeter • RF Signal Generator, 2 GHz • Oscilloscope • RF Load, 50 Ω, 25 Watts • Audio generator • Stereo generator/coder • Audio analyzer/noise/distortion • Stereo demodulator/modulation monitor 7.3 ROUTINE MAINTENANCE The Series 5200 STL Transmitter and Receiver should require no routine maintenance. As equipment and systems external to the Transmitter and Receiver change, minor audio level adjustments may be necessary. 7.3.1 CALIBRATION The Series 5200 STL Transmitter and Receiver do not require routine calibration. 7.4 DIAGNOSTICS AND REPAIR Before attempting repair, the tools and test equipment listed in Section 7.2 should be on hand. Only limited diagnostics and repairs can be accomplished without a complete set of equipment listed. The most practical repair philosophy is by the factory. It is recommended that a stand-by unit be on hand, together with an alternative plan for operation while factory repairs are being made. Spares kits are available from the factory. Rental and emergency units are available from the factory during repairs. Some general (and very important) observations on repair: 1. The STL equipment uses static sensitive components. ESD (Electrostatic Discharge) precautions must therefore be observed during repairs. This is extremely important. 2. The Theory of Operation Section (Section VI) is helpful in understanding how the equipment functions and will help you with diagnostics, as it covers the jobs performed by each major component and subsystem. 7.5 TFT CUSTOMER SERVICE DEPARTMENT TFT emergency service is available 24 hours a day.
