1-port reflection measurement that uses Inverse Fourier
Distance to Fault
o
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 on page 30.
Displays both a Return Loss measurement and a DTF
Return Loss & DTF
o
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 on page 26.
Calibrations are applied to both traces.
o
When in Hold mode and Single sweep is performed, only the active trace is
o
triggered. Use the ▲|▼ arrows to activate a trace.
1-port reflection measurement that displays the amount of
Return Loss
o
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 page 25.
(Voltage Standing Wave Ratio – also known as SWR) 1-port reflection
VSWR
o
measurement that displays the ratio of the maximum reflected voltage over the
minimum reflected voltage. The higher the trace is on the screen, the more
energy being reflected back to the FieldFox.

that accurately displays the loss through a cable or other device in dB. Both
ends of the cable must be connected to the FieldFox. NO phase information is
included in this measurement. Learn more on page 28.
