Example
smu.measure.func = smu.FUNC_DC_VOLTAGE
smu.measure.math.format = smu.MATH_MXB
smu.measure.math.mxb.mfactor = 0.80
smu.measure.math.mxb.bfactor = 50
smu.measure.math.enable = smu.ON
Set the measurement function to voltage.
Set the math operation to mx+b.
Set the scale factor for the mx +b operation
to 0.80.
Set the offset factor to 50.
Enable the math function.
