Setting mX+b units
The <name> parameter for CALCulate:KMATh:MUNits can be one or two characters
enclosed in single or double quotes. A character can be any letter of the alphabet, the degrees
symbol (°) or the ohms symbol (Ω).
The ohms symbol (Ω) and the degrees symbol (°) are not ASCII characters and therefore,
must be substituted with the '[' and '\' characters as follows:
CALCulate:KMAth:MUNits '['
CALCulate:KMAth:MUNits '\'

Description
Select calculation; NONE, MXB or PERCent.
Path to configure mX+b and Percent:
Specify scale factor (M) for mX+b: –100e6 to 100e6.
Specify offset (B) for mX+b: -100e6 to 100e6.
Specify units for mX+b: see
Specify reference value for Percent: –100e6 to 100e6.
Use input signal as reference value.
Enable or disable the selected calculation.
Query last calculation result.
Trigger a reading and query the calculation result.
Use ohms symbol (Ω) as units designator.
Use degrees symbol (°) as units designator.
