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.
To enable mask test order Option LMT at time of oscilloscope purchase, or order
DSOX2MASK as a stand-alone item after oscilloscope purchase.
To create a mask from a "golden" waveform (Automask)
A golden waveform meets all chosen parameters, and it is the waveform to which
all others will be compared.
1 Configure the oscilloscope to display the golden waveform.
2 Press the [Analyze] key.
3 Press Features ; then, select Mask Test .
4 Press Features again to enable mask testing.
