SECTION 4: FACTORY TEST PROCEDURE M64450G25-FCCRpt.doc Page 36 Transmitter Power Step 1 Set the Service Monitor to measure the transmitter frequency of the base station. Step 2 Set the Service Monitor filters to “<20 Hz HPF” and “15 kHz HPF”.  Ensure the Service Monitor can handle the full power transmission of the base station otherwise attach an attenuator to the output of the base station transmitter antenna port before transmitting into the Service Monitor. Step 3 Connect a coaxial cable from the output of the base station (or connected attenuator) to the Service Monitor’s RF In port. Step 4 In IPMessage, type the command “X = 1400,20”. The base station will transmit 20 packets of 1400 bytes each. This continuous transmission will last approximately 10 seconds. Step 5 On the Service Monitor note the transmitter power at the beginning of the transmission and observe whether the transmitter power drops over the course of the transmission. Step 6 Transmitter Power Output must begin at a level between 20 and 35 watts and must not drop by more then 5 watts over the course of the “X = 1400,20” command. Step 7 To change the transmitter output power use “TXpower” command in IPMessage. Step 8 Record the Transmit Power on the Tune and Align Data Sheet. Transmitter Data Quality and Message Success Rate Step 1 Connect a base station to an IPNC via SLIP cable or Ethernet. Step 2 Connect the mobile radio under test in the test set up. Step 3 Allow the mobile radio to connect to the base station. Step 4 Run IPLinkView or ping the mobile from the IPNC. Step 5 Set the downlink and uplink RSSI to -90 +/- 2dBm. Step 6 Observe the data quality reported by the base station on the uplink. Step 7 Adjust RV1 in the mobile for the maximum data quality on the uplink.

The MSR shall be greater that 94%. Step 10 Record the Data Quality and the MSR on the Tune and Align Data Sheet. If MSR does not meet 94% proceed with Hardware Time Verification for trouble shooting.
SECTION 4: FACTORY TEST PROCEDURE M64450G25-FCCRpt.doc Page 37 Step 11 After completion of Data Quality and MSR tuning, record Firmware Settings. File the Tune and Align Data Sheet with the Firmware setting in the IPMN Network. Hardware Timing Troubleshooting For trouble shooting data quality and MSR failures hardware timing can be verified as follows. The figure below is an oscilloscope plot of a down-link data message from the base station to the mobile. Channel 1 is connected to the mobile's RSSI test point, Channel 2 is connected to the mobile's recovered modulation (TP1), and Channel 3 is connected to the mobile’s modem chip select line. The scope’s acquisition mode is high-resolution. As can be seen from this plot, the base station's transmit carrier has ramped up to full power (Channel 1) in just a few milliseconds. The recovered modulation (Channel 2) is stable by this time. There follows a few milliseconds of quiet time followed by 12 milliseconds of symbol sync time. The recovered modulation from a base station should look similar to this plot. The recovered modulation signal should be approximately 1.0 Volts peak-to-peak and should be centered at approximately 2.5 VDC as is indicated in the figure above. Below is another oscilloscope plot of an up-link data message from the mobile radio to the base station. As in the last plot, Channel 1 is connected to the mobile's RSSI test point, Channel 2 is connected to the mobile's recovered modulation test point (TP1), and Channel 3 is connected to the mobile's modem chip select line. The scope's acquisition mode is now in the peak detect mode. This enables the mobile’s modem CS (Chip Select) line to be viewed.
SECTION 4: FACTORY TEST PROCEDURE M64450G25-FCCRpt.doc Page 38 The mobile radio’s microcontroller, upon detecting a step response in the RSSI (caused by the base station's transmitter coming up to power), waits a period of time equal to the programmed value of the mobile's carrier detect delay time. The microcontroller then instructs the modem to search for the modem synchronization preamble. When the base station instructs the modem to look for sync tones the modem's CS line transitions low. This can be seen in the above plot. Approximately 10 milliseconds after the base station's transmitter causes a step increase in the mobile's RSSI, the CS signal goes low momentarily. As can be seen, the sync tones are stable by this time and the modem quickly establishes synchronization. The figure below is a plot of the down-link timing characteristics. Channel 1 is connected to RSSI, Channel 2 is connected to recovered audio, and Channel 3 is connected to the modem CS pin. The scope is in the high resolution acquisition mode. Note there is a very short period of quiet time (no modulation) followed by approximately 12 milliseconds of modem synchronization time (sync time).
SECTION 4: FACTORY TEST PROCEDURE M64450G25-FCCRpt.doc Page 39 The next plot is the same as before but now the scope is in the peak detect acquisition mode. After the mobile radio detects a step response in the RSSI (caused by a down-link transmission), the mobile radio's microcontroller waits an amount of time equal to the programmed value of the "carrier detect delay time" then instructs the modem to look for frame sync. When the microcontroller instructs the modem to look for frame sync, it asserts the modem's CS line (active low). In this plot, the modem's CS line can be seen to transition low approximately 3 milliseconds after the base station's transmitter has come up to full power. The recovered modulation should be centered at approximately 2.5 VDC and should have the amplitude of approximately 800 mV peal-to-peak as indicated in the plot above.
SECTION 4: FACTORY TEST PROCEDURE M64450G25-FCCRpt.doc Page 40 Message Success Rate Testing and Burn-In After completion of the alignment and testing, the base station shall undergo Burn In and Final Testing. Install the mobile radio in the MSR screen room as shown in the figure below. Sequence Tests Step 1 In IPMessage, verify latest version of the mobile radio firmware by entering the ‘version’ command. Step 2 Verify the serial number and MAC I.D. – match the label on the unit by typing ‘serial number’ and ‘radio mac address’. Step 3 Modify firmware settings as needed and run IPLinkView on the mobile radio on the highest and lowest frequencies programmed in the mobile radio. Step 4 Run IPLinkView until a GPS connection is established. Step 5 Run ‘firmware check’ for the specific Customer.
SECTION 4: FACTORY TEST PROCEDURE M64450G25-FCCRpt.doc Page 41 Final Inspection The final inspection of the mobile radio is a critical step that translates directly into confidence in the product. Several areas must be checked on every base station before it can be shipped:  Screws- every screw hole must have the proper screw tightened the proper amount. The screws must be new and cannot have rounded shoulders. Screw heads must be flush to the case.  Connectors- all screws must be tight and the internal portions of each connector must not be damaged.  Covers and panels must not be dented or unduly scratched.  Initial traveler after completion of Final Inspection.
