Attenuation
The WB (wideband) single-ended attenuation test
allows you to calculate the dissipation of power of a
transmitted signal as it travels over the copper line.
This test is performed from one end of the cable and
does not require a remote second device. The test
does require an out-of-service wire pair that is open at
the far end. Faults should be repaired first.
Current Group
is the current test group name, for

Current Test
displays the test being measured.
Here you can switch to another test from the given
list. However, this action will terminate the
ongoing measurement test.

for the test. Available frequency bandwidths are:
2.2 MHz
, 8

, and
30 MHz
.
