:CHANnel<n>:INVert
Syntax :CHANnel<n>:INVert <bool>
:CHANnel<n>:INVert?
Description Enable or disable the waveform invert of the specified channel or query the status of the
waveform invert of the specified channel.
Parameter
Name
Type
Range
Default
<n> Discrete {1|2|3|4} --
<bool>
Bool
{{1|ON}|{0|OFF}}
0|OFF
Explanation When waveform invert is turned off, the waveform display is normal; when waveform
invert is turned on, the waveform voltage values are inverted.
Return
Format
The query returns 1 or 0.
Example
:CHANnel1:INVert ON /*Enable the waveform invert of CH1*/
:CHANnel1:INVert? /*The query returns 1*/
:CHANnel<n>:OFFSet
Syntax :CHANnel<n>:OFFSet <offset>
:CHANnel<n>:OFFSet?
Description
Set or query the vertical offset of the specified channel. The default unit is V.
Parameter
Name
Type
Range
Default
<n> Discrete {1|2|3|4} --
<offset> Real
Related to the current vertical scale and
probe ratio
When the probe ratio is 1X,
vertical scale≥500mV/div: -100V to +100V
vertical scale<500mV/div: -2V to +2V
When the probe ratio is 10X,
vertical scale≥5V/div: -1000V to +1000V
vertical scale<5V/div: -20V to +20V
0V (the probe
ratio is 10X)
Return
Format
The query returns the vertical offset in scientific notation.
Example
:CHANnel1:OFFSet 0.01 /*Set the vertical offset of CH1 to 10mV*/
:CHANnel1:OFFSet? /*The query returns 1.000000e-02*/
