Details
This attribute specifies the offset (b) for an mx + b operation.
The mx + b math operation lets you manipulate normal display readings (x) mathematically based on
the calculation:
y = mx + b
Where:
•
y is the displayed result
•
m is a user-defined constant for the scale factor
•
x is the measurement reading (if you are using a relative offset, this is the measurement with
relative offset applied)
•
b is the user-defined constant for the offset factor
If you send this command without the
<function>
parameter, it will set the scale factor for all
measure functions.
Example
:CALC:VOLT:MATH:FORM MXB
: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.
