Mask Tests; Actions - LeCroy SDA Operator's Manual

In Dual Parameter Compare mode, your X-Stream scope gives you the option to compare to
each other parameter results measured on two different waveforms. You can set your test to be
true if Any waveform or All waveforms fit the criterion stipulated by the comparison condition.
Your setup is conveniently shown in the Summary box of the Qx dialog. For example:

Mask Tests

You have the choice to do mask testing by using an existing mask, or by using a mask created
from your actual waveform, with vertical and horizontal tolerances that you define. Existing masks
can be loaded from a floppy disk or from a network.
You can set your mask test to be True for waveforms All In, All Out, Any In, or Any Out. For
example, if you select All In, the test will be False if even a single waveform falls outside the
mask.
Masks that you create from your waveform can be confined to just a portion of the trace by use of
a measure gate. (See Measure Gate for an explanation of how this feature works.)

Actions

By touching the Stop Test checkbox
"Actions" dialog, you can set up the test to end after a predetermined number of sweeps that you
decide.
You can also decide the actions to occur upon your waveforms' passing or failing, by selecting
one or all of the following:
•
stop
•
audible alarm
•
print image of display
•
emit pulse
•
save waveform
The selection Pulse
the front of the scope. This pulse can be used to trigger another scope. You can set the amplitude
and width of the pulse as described in the Auxiliary Output Signals section of this manual.
Depending on your scope model, you can configure up to 8 pass/fail conditions.
