RF Cable Sweeps Procedure
This section provides step-by-step procedures for calibrating the test equipment and performing
insertion loss measurements of the RF cable. Refer to Figure O15.
Step 1. Calibrate the test equipment.
Step 2. Connect Signal Generator to cable 1 on the RFS side to the RF cable.
Step 3. Connect spectrum analyzer to cable 1 on BTS side of RF cable. This will be done with
the test cable and the QMA/SMA adapter.
Step 4. Enable the RF on the signal generator.
Step 5. From the Delta marker found in Step 1 take the loss reading in db. Record the results.
Step 6. Perform steps 2 through 5 for all cables.

RFS Test Procedure
This procedure is performed twice for an installation. The first sweep is performed prior to
mounting the RFS on the tower. This test verifies that all the equipment is in tact from shipment.
These sweeps will need to be compared to the factory sweeps that are shipped with the RFS.
The second sweep is performed after the RFS has been mounted on the tower and the RF cables
have been connected. This sweep verifies that no damage was done to the RFS when hoisting it,
and that the RF cables are properly connected to the RFS.
Step 1. Perform the “Equipment Set-up”.
Note: When performing the transmit (TX) side tests on the RFS, the signal level from
the Signal Generator needs to be lowered to at least –20 dB. The RFS has protection
circuits built in and will disable the PAs in the RFS if the incoming signal is too high.
Step 2. Perform the “Equipment Calibration”.
Step 3. Configure the test equipment as shown in Figure O16.
