Note: The position of the RFS will vary the sweep results due to reflections from the test
surface.
Step 8. 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 the one shown in Figure K10.

Step 9. The marker value should be equal to the RFS Only Rx 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 10. Record the data in the RFS System Test Form under “RFS RX PATH LOSS (RFS
ONLY)”. Ensure that the information is recorded under the channel number that is on
the RFS antenna that is being tested.
Step 11. Repeat steps 5 through 7 for the remaining seven antenna inputs on the RFS.
Step 12. Change the frequency 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.
