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
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.
