DTF (Distance to Fault) Measurements
DTF Measurement Settings
1.8 GHz = 0.18 dB/m
2 GHz = 0.2 dB/m
The correction for loss at 5 meters in one direction: 0.18 dB/m * 5m = 0.9 dB.
All DTF measurements correct for loss for travel down the DUT and back, so
double the correction: 0.9 dB * 2 = 1.8 dB.

Window Settings
