CALCulate:MATH:EXPRession
<(VALUE1,VALUE2)|(MEAS,VALUE2)|(VALUE1,MEAS)>
DESCRIPTION:
This command specifies which expression is used by the
CALCulate block. The parameters are the offset and the
scale factors respectively.
MEASure refers to the previous measurement. <value1> and
<value2> are the offset and scale factors.
If MEASure is specified for the offset value, then the previous
measurement is used as the offset. If MEASure is specified
for the scale factor, then the previous measurement is used
as the scale factor. Note that at power-up, the default value
of the previous measurement is zero.
The permitted number of significant digits for <value1> and
<value2> is 9. The display range is from 9.99999999E±9 to
-9.99999999E±9.
The following algorithm will be invoked
