ITU-T standard masks. Each mask
sets the oscilloscope vertical, horizon-
tal, and trigger controls to acquire that
standard’s waveform.
You can also select ITU-T standard
masks in the Telecom QuickMenu.
After selecting a standard, push the
AUTOSET front-panel button to
position the waveform in the mask.
The oscilloscope is set to edge trigger
on waveforms (per ITU-T G.703
standard).
