This attribute specifies the constant to use when math operation is set to percent.
Type TSP-Link accessible
Attribute (RW) Yes
Usage
value = smu.measure.math.percent
smu.measure.math.percent = value
value
Details
This is the constant that is used when the math operation is set to percent for the selected measurement
function.
The percent math function displays measurements as percent deviation from a specified constant. The percent
calculation is:
Where:
• Percent is the result
• Input is the measurement (if relative offset is being used, this is the relative offset value)
• Reference is the user-specified constant
Example
smu.measure.func = smu.FUNC_DC_VOLTAGE
smu.measure.math.format =
smu.MATH_PERCENT
smu.measure.math.percent = 50
smu.measure.math.enable = smu.ON
