Example
smu.measure.func = smu.FUNC_DC_VOLTAGE
smu.measure.math.format =
smu.MATH_PERCENT
smu.measure.math.enable = smu.ON
When voltage measurements are made, the math
format is enabled and set to percent.

Usage
operation = smu.measure.math.format
smu.measure.math.format = operation
operation
Math operation to be performed on measurements:
• y = mx+b: smu.MATH_MXB
• Percent: smu.MATH_PERCENT
•
Reciprocal: smu.MATH_RECIPROCAL
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.
