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
If you send this command without the <function> parameter, it will set the constant for all measure
functions. It will not change the setting for a digitize function.
Example
CALC:VOLT:MATH:FORM PERC
CALC:VOLT:MATH:PERC 50
CALC:VOLT:MATH:STAT ON
Set the math operations for voltage to percent.
Set the percentage value to 50.
Enable math operations.

Usage
:CALCulate[1]:<function>:MATH:STATe <n>
:CALCulate[1]:<function>:MATH:STATe?
<function>
The measure function:
• Current: CURRent[:DC]
• Resistance: RESistance
• Voltage: VOLTage[:DC]
The digitize function:
• Digitize current: DIGitize:CURRent
• Digitize voltage:
DIGitize:VOLTage
<n>
Disable math operations:
OFF
or
0
Enable math operations: ON or 1
Details
When this command is set to on, the math operation specified by the math format command is
performed before completing a measurement.
If you send this command without the <function> parameter, it sets the state of math operations
for all measure functions. It will not change the setting for a digitize function.
