On DSOX1200-Series oscilloscopes, 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 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.
