Keysight N9938-90006 User's Guide
Distance To Fault 1-port reflection measurement that uses Inverse Fourier
Transform (IFT) calculations to determine and display the distance to, and
relative size of, a fault or disruption in the transmission line. Units are in
return loss format, expressed as a positive number in dB, unless the
measurement selected is DTF (VSWR). Learn more about DTF
Measurements refer to
Measurements.".
Return Loss & DTF Displays both a Return Loss measurement and a DTF
measurement. Use this format to display the frequency settings that are
used to make the DTF measurement. The frequency range settings for these
two measurements can be coupled or uncoupled. Learn more,
Frequency" on page 58.
— Calibrations are applied to both traces
— When in Hold mode and Single sweep is performed, only the active
trace is triggered. Use the
Return Loss 1-port reflection measurement that displays the amount of
incident signal energy MINUS the amount of energy that is reflected. The
higher the trace is on the screen, the more energy being reflected back to
the FieldFox. Learn how to measure Return Loss on
