Math and Measure
Math on Parameters
In addition to measuring waveforms, you can set up a parameter that performs mathematical
operations on other measurements.
The setup for Math on Parameters is much like that for other parameters. Some parameters can also
be qualified on the Accept dialog using value ranges or gating waveforms, as can regular waveform
measurements.
Math on Parameters differs from Math functions in that the input and the output are still numerical
values that display in the measurement readout table. Math functions, on the other hand, input and
output waveform traces that appear on the grid.
Exclusions
The parameter math feature prevents multiplication and division of parameters that return
logarithmic values.
Parameters that are already the result of parameter math operations are also excluded. If they are
included in a remote control setup command, an error message is generated and the setup canceled.
Set Up Math on Parameters
1. From the menu bar, choose
Measure > Measure Setup...
.
2. Choose Measure Mode
My Measure
and open a parameter setup (P
x
) dialog.
3. Touch the
Math on Parameters
button.
4. Touch
Math Operator
and choose an operation from the
Select Measurement
menu.
5. Touch the
Source
fields and select the parameters that are the inputs to the measurement.
These should be other parameters than that you are now using for Math on Parameters.
6. Check
On
to enable the new output parameter and add it to the measurement readout.
