SECTION 4: FACTORY TEST PROCEDURE 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.
SECTION 4: FACTORY TEST PROCEDURE 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.
SECTION 4: FACTORY TEST PROCEDURE 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.
SECTION 4: FACTORY TEST PROCEDURE 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).
SECTION 4: FACTORY TEST PROCEDURE 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’.
SECTION 4: FACTORY TEST PROCEDURE 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.
