Syntax
CH<x>:INVert {
ON|OFF}
CH<x>:INVert?
Arguments
OFF sets the invert function for channel <x> to off.
ON sets the invert function for channel <x> to on.
Examples
CH4:INVert ON inverts the waveform on channel 4.
CH2:INVert? might return :
CH2:INVERT 0
indicating that channel 2 is not
inverted.
CH<x>:LABel
This command specifies the waveform label for channel <x>, where x is the
channel number (1–4).

Syntax
CH<x>:LABel <Qstring>
CH<x>:LABel?
Arguments
<Qstring> is an alphanumeric string of text, enclosed in quotes, that contains the
text label information for the channel <x> waveform. The text string is limited
to 30 characters.
CH<x>:OFFSet
This command specifies the vertical offset for channel <x>, where x is the channel
number (1–4).
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 signalfor
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 acquis
ition window for channel
waveforms to help determine what data is acquired. The oscilloscope always
displays the input signal minus the offset value.
The channel offset range depends on the vertical scale factor.
