Agilent Technologies FieldFox N9913A - Time Domain (Transform) Settings; Transform Settings Table

54 FieldFox User’s Guide
The frequency domain of an S11 measurement shows reflections caused by
mismatches in the cable. It is impossible to determine where the mismatches
physically occur in the cable.
The Time Domain response shows both the location and the magnitude of each
mismatch. The responses indicate that the second cable bend is the location of a
significant mismatch. This mismatch can be gated out, allowing you to view the
frequency domain response as if the mismatch were not present. Learn more
about gating on page 59.
Markers that are created on a Time Domain trace can be used to pinpoint the
distance of the mismatch from the reference plane.
