:CALCulate:SUB:VOFFset
Syntax
:CALCulate:SUB:VOFFset <offs>
:CALCulate:SUB:VOFFset?
Description
Sets or queries the vertical position of the subtraction operation waveform. The unit is related to the current
amplitude unit of the source channel.
Parameter

(40 x vertical scale of the subtraction operation waveform)
0
Return Format
The query returns the vertical position in scientific notation.
:CALCulate:SUB:VSCale
Syntax
:CALCulate:SUB:VSCale <scale>
:CALCulate:SUB:VSCale?
Description
Sets or queries the vertical scale of the subtraction operation waveform. The unit is related to the current
amplitude unit of the source channel.
Parameter

Default
<scale> Real Refer to
Remarks
2 V/div
Remarks
The default range of <scale> is from 1 pV/div to 200 V/div. Its actual range is related to the vertical scale of
the source channel (refer to the :CHANnel<n>:SCALe command), at 1-2-5 step.
Note: After the vertical scale of the source channel is modified, the range of <scale> will not be changed
until the subtraction operation is re-enabled.
Return Format
The query returns the vertical scale in scientific notation.
