CH<x>:INVert
Sets or queries the inversion state of the specified instrument channel. The value
of <x> can vary from 1 through 4 depending on the instrument model.
This command is equivalent to setting the Invert option in the Vertical channel
menus.

Syntax
CH<x>:INVert {ON|OFF}
CH<x>:INVert?
Arguments
ON inverts the specified instrument channel.
OFF sets the specified instrument channel to noninverted.
Examples
CH1:INVERT ON inverts the signal on channel 1.
CH2:INVERT? might return :CH2:INVERT 0, indicating that channel 2 is not
inverted.
CH<x>:OFFSet
Sets or queries the vertical offset for channel <x>, where x is the channel number.
This command offsets the vertical acquisition window (moves the level at the
vertical center of the acquisition window) for the specified channel. Visualize
offset as scrolling the acquisition window towards the top of a large signal for
increased offset values, and scrolling towards the bottom for decreased offset
values. The resolution of the vertical window sets the offset increment for this
control.
Offset adjusts only the vertical center of the acquisition window for channel
waveforms to help determine what data is acquired. The instrument always
displays the input signal minus the offset value.
The channel offset range depends on the vertical scale factor. The valid ranges
for the instrument are (when the probe and external attenuation factor is X1):
For V/Div settings from 2 mV/div to 200 mV/div, the offset range is +/- 0.8 V
For V/Div settings from 202 mV/div to 5 V/div, the offset range is +/- 20 V
