6.2 Mathematical Functions and Formulas
You can enter mathematical expressions using two different modes:
●
"Optimized": a graphical editor allows you to define a simple math function quickly by
selecting the source waveform(s) and the operator: chapter 6.2.1, "Optimized Graph-
ical Editor", on page 185.
●
"Advanced": a formula editor allows you to define sophisticated math functions freely,
as required to your needs: chapter 6.2.2, "Advanced Expressions", on page 187.
SCPI command:
● CALCulate:MATH<m>[:EXPRession][:DEFine] on page 575
6.2.1 Optimized Graphical Editor
In the optimized editor, you can define the most common mathematical formulas without
knowing their correct syntax.
6.2.1.1 Defining a Formula in the Optimized Graphical Editor
1. In the "Math" menu, select "Math Setup", or press the MATH key.
2. In the "Setup" tab, select the "Optimized" tab.
3. Tap the "Source 1" and "Source 2" icons and select the signal source(s) to which the
math function will be applied. For details on available signal sources, see "Source 1 /
2" on page 186.
4. Tap the "Operator" icon and select the mathematical function.
For details on available operators, see "Operator" on page 186.
5. If the operator requires additional parameters, enter them in the input fields.
