Building a Mask File 280
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 DSOX4MASK 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.
