Math calculations that you can apply to measurements
The Series 2280 supports mx+b built-in math calculations. Math calculations are applied to the input
signal after filter and relative offset operations are completed. For more details on the order of
operations, see Displayed measurements (on page 4-15).
Math operations apply to the selected measurement function. If you change the measurement
function, the math operation for that measurement function becomes active.
When you select the concurrent measurement function, math operations only apply to current
measurements and do not affect voltage measurements.
mx+b
The mx+b math operation lets you manipulate normal display readings (x) mathematically based on
the following calculation:
mx + b = Y
Where:
m = A user-defined constant for the scale factor
x = The measurement reading (if you are using a relative offset, this is the measurement with relative
offset applied)
b = A user-defined constant for the offset factor
Y = The displayed result
When the mx+b math operation is active, the unit of measure for the front-panel voltage and current
readings defaults to the character X and the CALC indicator is displayed to the right of the
measurement.
The CALC indicator represents the filter and mx+b operation status. If filter or math operation is
enabled, the CALC indicator is displayed to the right of the measurement.
