Select and Run the Test
Perform TX Test Port Calibration utility operations as follows:
NOTE This procedure might include steps that prompt you to disconnect cables from the site
antenna ports and make connections to the Test Set. Before removing or re-installing the
antenna cables, make certain that the transmitter has been turned off by the MSC (or by
switch personnel if not using a modem). The green ACT LEDs on the ADU and BCR
modules indicate that the transmitter is active, and therefore should be off before
disconnecting cables.
Step 1. From the Lucent CDMA Tests Main Menu screen, select the Calibration/Utilities
field. The Test Software will display the Calibration/Utilities Menu screen.
Step 2. Select the TX Test Port Calibration field.
Step 3. Select full or specified calibration.
Step 4. Follow the directions on the screen.
Step 5. Connect the Test Set to the Base Station as indicated and press the
k1 (Proceed) key to
continue after each setup.
• Full calibration requires two separate measurement setups. Make certain to use the
correct test cables for each setup.
• Specified calibration uses one measurement setup. Make certain to use the TX Test
Port cable when making the measurement.
Review the Results
The Test Software will calculate and display the Base Station TX Test Port coupling
factor. You should write this value next to the TX Test Port for future reference.
If you select the Test Configuration field (from the Lucent CDMA Tests Main Menu
screen), note that the TX Test Port Coupling Factor [dB] field now contains the
value determined by the test.
Press the
k1 (Proceed) key to return to the Calibration/Utilities Menu screen, then press
the
k5 (Return) key to return to the Lucent CDMA Tests Main Menu screen.
