Limit Testing (non-EDU models only)
You can use the oscilloscope to monitor an active input signal against a template
and to output pass or fail results by judging whether the input signal is within the
bounds of the template.
Use the limit test if you need a Pass/Fail test to determine if a signal is good. Set
up the oscilloscope to automatically monitor a source signals and output Pass
or Fail results by evaluating whether or not the acquired waveform falls within
predeļ¬ned boundaries. The limit test feature allows you to create templates based
on one or two independent reference waveforms. If a failure is detected, a series
of speciļ¬cactionscanbetriggered.
1. Push the front-panel Function button.
2. Select Limit Test from the resulting side menu to bring up the limit testing
menu.
3. Select Source from the side menu to deļ¬ne the source of the waveform to
compare against the limit test template.
4. Select Compare To to specify the limit test template against w hich to
compare test signals sectioned with the Source menu item.
5. Push Template Setup from the side menu to deļ¬ne the boundary to compare
with the input source signals.
If you pushed Template Setup, you can create the template with speciļ¬c
horizontal and vertical tolerances. You can create them from channel 1,
channel 2, or the Math waveform. On page 2 of the resulting m enu you can
push Display Template and toggle between On and Off to display o r not
a stored template. Push Back from page 2 to return to the top level of the
limit test menu.
6. Push - more - page 1 of 2 to see the Action on Violation side-menu button.
Select it and then select an action from the resulting side menu to describe
what the oscilloscope will do after it detects a violation. You can select
between Save Waveform and Save Image.PushBack to return to the top
level o f the limit test menu.
7. Push the Stop After butt
on from page 2 of the top level of the limit test menu.
Push the button with the same name on the resulting s ide m enu. On the
resulting pop-out menu, turn and push the Multipurpose knobtodeļ¬ne the
conditions that will stop limit testing. If you select Waveforms, Violations,
