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
prede
fi
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 speci
fi
c actions can be triggered.
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 de
fi
ne the source of the waveform to
compare against the limit test template.
4.
Select
Compare To
to specify the limit test template against which to
compare test signals sectioned with the
Source
menu item.
5.
Push
Template Setup
from the side menu to de
fi
ne the boundary to compare
with the input source signals.
If you pushed
Template Setup
, you can create the template with speci
fi
c
horizontal and vertical tolerances. You can create them from channel 1,
channel 2, or the Math waveform. On page 2 of the resulting menu you can
push
Display Template
and toggle between
On
and
Off
to display or not
a stored template. Push
Back
from page 2 to return to the top level of the
limit test menu.

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
