Impulse Duration
Impulse Duration
The Impulse Duration is a histogram displaying the distribution of
different captured impulse durations (widths) over a period of time. This is
very useful if different types of impulse noises are occurring at different
times. It also provides a Disruption graph showing the total accumulated
durations of impulse events over a period of time.
Impulse Duration
On the Impulse Duration page, the test histogram plots impulse Counts
(y-axis) vs. Impulse Duration (x-axis), showing the distribution of different
duration impulses over time. This is key to understand when short events
such as REIN occur, versus longer events (PEIN) or short high impulse
noise events (SHINE). The page also records the Elapsed Time, Total
Counts, and pass/fail status. The test 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.
To access the Impulse Duration page:
1. From the Copper main menu Test Groups, select Impulse test
.
2. From the Tests menu, select Impulse Duration to open the page and
start the test.
3. Use the graph controls to maneuver the graph. Refer to Graph Controls
on page 19 for more information.
