Zoom C ommand Group
Zoom commands let you expand and position the waveform display horizontally
and vertically, without changing the time base or vertical settings.

as a z oom source, which enables you to zoom in on a zoomed waveform.
Command
Description
ZOOm Resets the zoom transforms to default values
for all traces or live traces. Th
e ZOOm query
returns the current vertical and horizontal
positioning and scaling of the display
ZOOm:GRA ticule:SIZE Sets or returns the size of the zoom graticule
ZOOm:HORizontal:POSition Sets or queries the horizontal position around
which the zoom waveform is dis
played.
It is freely movable within the confines of
the acquired waveform (0% to 100%) and
measured from left to right o
f the acquired
waveform
