EXAMPLES OF AN ANTENNA FREQUENCY RESPONSE SWEEP IN RETURN LOSS AND VSWR.
Using Markers and a limit line allows for a quick and accurate reading. Nothing has been changed in each sweep except for the Mode from ReturnLoss to SWR.

Distance to Fault (DTF) will pinpoint where the problem occurs.
Need to know the frequency of operation, cable type, and the distance from the transmitter to the antenna.
Add 10-20% additional length to the Stop Distance. It is also very helpful to have a diagram of your system so that components can be identied.
It is not always possible to have such a diagram.
DISTANCE TO FAULT
1. Select DTF_RL or DTF_SWR mode.
2. Select Points. (See step 5 of measure match).
3. Set start and stop frequency. Refer to step 2 in
measure/match.
