Mask Testing
Mask testing is available on the DSOX1000-Series oscilloscope models.
One way to verify a waveform's compliance to a particular set of parameters is to
use mask testing. A mask defines a region of the oscilloscope's display in which
the waveform must remain in order to comply with chosen parameters.
Compliance to the mask is verified point-by-point across the display. Mask test
operates on displayed analog channels; it does not operate on channels that are
not displayed.
Creating/Editing Mask Files

• Mask File Identifier.
•Mask Title.
