Step 6. Take a marker measurement on the Spectrum Analyzer by using the ‘marker to peak’
or the ‘peak search’ function. The screen on the Spectrum Analyzer should look
similar to that shown in Figure O3.
Figure O3: Sweep Test Marker Measurement Example
If the marker measurement doesn’t read 0.0 dBm, adjust the amplitude on the Signal Generator
until the Spectrum Analyzer marker reads 0.0 dBm, or as close to 0.0 dBm as possible. This will
remove all losses associated with the test cables. All measurement data should be recorded one
digit to the right of the decimal point, for example, 31.5dB.
Once the test setup is calibrated, these cables will remain in place and will be used
throughout the whole test. If the test cables are removed or changed, incorrect readings
will result.
RF Cable Insertion Loss
This test is performed on all RF cables that are installed in the system. This includes the eight
antenna cables, the system calibration cable, and all jumper cables. Follow the procedures for
either the cables on the ground or cables run up the tower.
Test Procedure For RF Cables on the Ground
Step 1. Ensure calibration of the test setup has been performed each time the test frequency is
changed.
Step 2. If present, remove the barrel connector from between the Signal Generator and
Spectrum Analyzer cables.
Step 3. Connect the cable from the Signal Generator to one end of the cable. Use a barrel
connector to change the gender, if required.
Step 4. Connect the cable from the Spectrum Analyzer to the other end of the cable. Use a
barrel connector to change the gender, if required.
