Functions
Details
This specifies which math operation is performed on measurements for the selected measurement
function.
You can choose one of the following math operations:
• y = mx+b: Manipulate normal display readings by adjusting the m and b factors.
• Percent: Displays measurements as the percentage of deviation from a specified reference constant.
• Reciprocal: The reciprocal math operation displays measurement values as reciprocals. The displayed
value is 1/X, where X is the measurement value (if relative offset is being used, this is the measured
value with relative offset applied).
Math calculations are applied to the input signal after relative offset and before limit tests.
Example
: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.
