Usage
:CALCulate[1]:<function>:MATH:MMFactor <n>
:CALCulate[1]:<function>:MATH:MMFactor?
<function>
<n>
Details
This command sets the scale factor (m) for an mx + b operation for the selected measurement function.
The mx+b math operation lets you manipulate normal display readings (x) mathematically according to the
following calculation:
y = mx + b
Where:
• y is the displayed result
• m is a user-defined constant for the scale factor
• x is the measurement reading (if you are using a relative offset, this is the measurement with relative
offset applied)
• b is the user-defined constant for the offset factor
If you send this command without the <function> parameter, it will set the scale factor for all
functions.

:CALC:VOLT:MATH:FORM MXB
:CALC:VOLT:MATH:MMF 0.80
:CALC:VOLT:MATH:MBF 50
