WB Impulse Noise
WB Impulse Noise
The wideband impulse noise test allows you to measure impulse noise on
the circuit under test.
Count
The
Count
function displays and updates results in
real time
, for the length of time set in
Test Duration
or
less if you stop the test. The last valid results then
remain displayed.
Current Group
is the current test group name, for
example

.
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.
WB Noise Filter
displays the filter currently
enabled. Options are:

Termination Resistance
lists the resistance of the dummy load
connected to the line.
Test Duration
allows you to set the length of time to run the test from a
list of values.
Impulse Separation Time
(IST) specifies the time interval between
successive impulses. Some impulse events comprise many sub-pulses
or a pulse-train. Use a larger IST to capture longer events of many
sub-pulses, or a smaller IST between events to capture fast sub-pulses
as separate impulse events.
Threshold Settings
button opens a new page that allows you to set the
Power Detection Level
and
WB Impulse Noise
thresholds.
