Step 5. 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 O4.

Step 6. The result should be within +/– 0.5 dB of the calculated value. If the insertion loss
results do not agree with the manufacturer’s data, check the connectors for proper
connection to the cable, and check for kinks in the cable. If the Spectrum Analyzer has
a distance to fault (DTF) function, it can be used to help troubleshoot kinks in the
cable.
CAUTION! Cables with results greater than the specified limits (i.e., 2 or 3 dB high)
should not be installed, as a potential hardware fault exists.
Step 7. Record the data in the RFS System Test Form under “MAIN FEEDER LOSS” or
“JUMPER LOSS”. Ensure that the information is recorded under the channel number
that is on the cable label.
Step 8. Repeat steps 3 through 7 for all remaining cables and jumpers.
Step 9. Change the frequency to the next test frequency (refer back to the Test Setup section of
these procedures). Perform steps 1 through 8 until all cables have been successfully
tested at the frequencies shown in Table O4.
