Examples
CH4:INVert ON i
nverts the waveform on channel 4.
CH2:INVert? might return :C H2:INVERT 0 indicating that channel 2 is not
inverted.
CH<x>:LABel
Sets or returns the waveform label for channel <x>, where x is the channel number.
Group
Vertical
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
Sets or returns 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 v alues, 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 d etermine what data is acquired. The osc illoscope always
displays the input signal minus the offset value.
The channel offset range depends on the vertical scale factor.
