Cable Fault Location
Video BW
Used to set the video bandwidth used for the measurement and
to define whether it is automatic or manual. The default values
are 3 MHz and Auto.
TG Amplitude
Used to set the power level of the internal source. The default
output level is –10 dBm.
Span Changes the frequency span used when acquiring the trace data
prior to the FFT. This, in conjunction with Trace Points and
Velocity Factor, has a direct effect on the maximum distance
that can be measured and the subsequent span resolution. Span
is provided for use in conjunction with
Center Freq , under
FREQUENCY,
when measuring DUTs that have limited or
restricted bandpass characteristics.
