Math calculations are applied to the input signal after relative offset and before limit tests.
If you send this command without the
<function>
parameter, it will set the state of the math format
for all measure functions.
Example
:CALC:VOLT:MATH:FORM MXB
:CALC:VOLT:MATH:MMF 0.80
:CALC:VOLT:MATH:MBF 50
:CALC:VOLT:MATH:STAT ON
Set the math function for voltage measurements to mx+b.
Set the scale factor for voltage measurements to 0.80.
Set the offset factor to 50.
Enable the math function.
