Result Details Cable Configuration
The Cable Configuration page in the Results Details
allows you to view the cable parameters set for the WB
Attenuation test.
No. of Cable Sections is the number of
consecutive cable sections, with a maximum of
4.
Cable Type # displays the number of a cable
section set above, ID, Cable Name and Fill.
Section Length identifies the cable length of
each section.
12.5 Return Loss
The Return Loss test allows you to measure the loss of
power in the signal returned/reflected by a discontinuity
in a transmission line. This discontinuity or impedance
variation can be a mismatch with the terminating load
or with a device inserted in the line.
A small value dBRL number means that most of the
pulse energy is reflected by the cable fault. An open or
short would reflect all the energy so its return loss is
zero.
Remember, the larger the dBRL reading, the smaller the
problem and vice versa.
Single Frequency
The Single Frequency test is continuous, and allows
you to configure parameters and change values during
the measurement. The page provides a Return Loss
result value in dB, and pass/fail status.

Current Group is the current test group name,
for example Frequency Tests.
Current Test displays the test being
measured. Here you can switch to another
Frequency test from the given list. However,
this action will terminate the ongoing
measurement test.
Frequency allows you to set the frequency
value for the Return Loss test.
Frequency Step lists a choice of frequency
step values.
Termination Resistance lists a choice of
resistance values for the termination of the
signal.
Threshold Settings button opens a new page
that allows you to set Return Loss thresholds
for the transmission.
Result displays the pass/fail status, Return
Loss and Frequency (TX) values.
Test Status displays the current state of
measurement or an error message.
