To view the template you have created, press the MORE button. Then press
the button corresponding to the destination reference memory you have used.
The waveform appears on the display.

NOTE. To view the waveform data as well as the template envelope, it might be
useful to select the Dots display style. (See Select the Display Style on
page 3–39.)

Now specify the channel that will acquire the waveforms to be compared against
the template you have created:

1. Press SHIFT ACQUIRE MENU ➞ Limit Test Sources (main) ➞

Compare Ch1 to, Compare Ch2 to, Compare Ch3 to, Compare Ch4 to,
Compare Math1 to, Compare Math2 to or Compare Math3 to (side).

2. Once you have selected one of the four channels or a math waveform as a

waveform source from the side menu, press the same side menu button to
select one of the reference memories in which you have stored a template.

Valid selections are any of the four reference waveforms Ref1 through Ref4
or None. Choosing None turns limit testing off for the specified channel or
math waveform.

If you have created more than one template, you can compare one channel to
one template and the other channel to another template.

Now specify the action to take if waveform data exceeds the limits set by the
limit test template and turn on limit testing:

1. Press SHIFT ACQUIRE MENU ➞ Limit Test Setup (main) to bring up a

side menu of possible actions.
