Step 5. The marker value should be equal to the RFS Only Tx insertion loss within ±2.0 dB,

per the manufacturer’s data. If the insertion loss results do not agree with the

manufacturer’s data, check the test setup.

Caution: An RFS with results greater than the ±2.0 dB limits should not be installed, as a

potential hardware fault exists. Contact Navini Networks Technical Support.

Step 6. Record the data in the RFS System Test Form under “RFS TX PATH LOSS (RFS

ONLY)”. Ensure that the information is recorded under the channel number of the RFS

antenna that is being tested.

Step 7. Repeat steps 5 and 6 for the remaining seven antenna inputs on the RFS.

Step 8. Change to the next test frequency (refer back to Test Setup). Perform steps 1 through 8

until the RFS has been successfully tested at the frequencies shown in Table K4.

RFS Only Receive Verification

Step 1. Ensure calibration of the test setup and RFS Test Box setup for RFS Only has been

performed each time the test frequency is changed.

Step 5. Switch the RFS Test Box to the Receive (Rx) mode.

Step 6. Connect the cable from the Signal Generator to the RFS cal connector. Use a barrel

connector to change the gender, if required.

Step 7. Connect the cable from the Spectrum Analyzer to the RFS antenna input number 1.

Use a barrel connector to change the gender, if required. See Figure K9.
