TDR (Time Domain Reflectometry) - Option 215
TDR Measurement Settings
The Loss value for the measurement is interpolated from the Freq/Loss pairs at
the Center Freq:
The correction for loss at 5 meters in one direction: 0.18 dB/m * 5m = 0.9 dB.
All TDR measurements correct for loss for travel down the DUT and back, so
double the correction: 0.9 dB * 2 = 1.8 dB.

Window Settings

Window settings provide the ability to choose between optimizing TDR
measurements for resolving closely-spaced faults or for the ability to measure
