Command Groups
2–34 TLS 216 Programmer Manual
Vertical Commands
Vertical commands control the display of groups, of their channels and wave-
forms, and or reference waveforms.
The logic scope stores and displays waveforms in groups, which contain one or
more channels each of which can contain one waveform. Use vertical commands
to vertically position, offset, scale, and otherwise manipulate groups of wave-
forms.
You must include a channel in a group to acquire (sample and digitize) its
waveform; channels not included in any group (or included in a group that is off)
can only be used as trigger sources.
