ZOOM:HORIZONTAL:SCALE?
might return 1.00E+0 as the horizontal scale factor.
ZOOm:STATE
Turns Zoom mode on and off. When Zoom mode is on, the horizontal and
vertical position and scale commands affect the waveform display, not the
acquisition. This is the only way to position and scale math and reference
waveforms. This command is equivalent to turning Zoom on and off in the
Zoom side menu.

STATE
PREView
OFF or <NR1> = 0 turns Zoom mode off.
ON or <NR1> 0 turns Zoom mode on. When InstaVu is in use, the state value
becomes a requested value, to be restored when InstaVu is switched off. Do not
use this condition if InstaVu is on. InstaVu overrides the zoom on state.
PREView (TDS 4XXA and 7XXA) sets ZOOM:STATE to preview. Also, it
causes the oscilloscope to display both the ZOOM:STATE OFF and
ZOOM:STATE ON traces simultaneously in dual, half-height graticules. Do not
use this condition if InstaVu is on. InstaVu overrides the zoom preview state.
ZOOM:STATE ON
enables the Zoom feature.
ZOOM:STATE?
returns either 0 or 1 (OFF, PREVIEW, or ON for the TDS 4XXA and 7XXA)
depending on the state of Zoom mode.
