Mask testing can be done 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 becomes 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. Refer to the Measure Gate
online help topic for more information on how this feature works.
Right-Hand Dialogs

On the Test right-hand dialog, make a selection in the Test is True
when group of buttons (as follows).
Note: The previous selection is for All In and means the test is False
when a single waveform falls outside the mask.
From the Show Markers section of the dialog, choose whether or
not to have mask violations displayed by touching either the Off or
On button, respectively.
