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 [Acquire] key.
3 Press the Mask Test softkey (in the Acquire Menu) to enter the Mask Test Menu.
4 Press the Automask softkey.
5 Press the Source softkey and ensure the analog channel from which to create the
mask is selected.
6 Adjust the mask’s horizontal tolerance (± Y) and vertical tolerance (± X). These are
adjustable in graticule divisions or in absolute units (volts or seconds), selectable
using the Units softkey.
