Mask Testing; To Create A Mask From A "Golden" Waveform (Automask) - Agilent Technologies InfiniiVision 3000 User Manual

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 DSOX3MASK 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.
