Step 6. Select the TX Antenna Port Cable Loss [dB] field, rotate the knob to the loss value
for the cable that you connect from the Test Set RF IN/OUT port to the Base Station TX
Antenna port, and press the knob to select it. If you are uncertain of the cable loss value,
run the “TX Antenna Port Cable Calibration Test” on page 75 to measure and enter the
value automatically.
Step 7. Select the TX Test Port Cable Loss [dB] field, rotate the knob to the loss value of the
cable that you connect from the Test Set ANT IN port to the Base Station TX Test Port,
and press the knob to select it. If you are uncertain of the cable loss value, run the “TX
Test Port Cable Calibration Test” on page 76 to measure and enter the value
automatically.
Step 8. Select the TX Antenna Port Coupling Factor [dB] field, rotate the knob to the value
of the loss through the directional coupler used to provide the transmitter signal to the
Base Station TX Test Port, and press the knob to select it. The Test Software will use this
value to calculate the transmitter true power output without the requirement for
disconnecting the transmit antenna from the TX Antenna port. If you are uncertain of
the coupling factor value, run the “TX Test Port Calibration Test” on page 77 to measure
and enter this value automatically.
