Math Expression
B2980 provides a math function for performing calculations using the
measurement result data. The calculation result can be displayed and used for the
limit test and trace statistics.
For the predefined math expressions, see “Predefined Math Expressions.”
To define a math expression, see the Keysight B2980 series SCPI Command
Reference. Math expressions can be defined by using the :CALC:MATH
commands. For resources effective for the expression, see “Resources Used in the
Expressions” on page 226.
To use the math function, see “Math Expression Dialog Box” on page 177.
To display the calculation result, see “Graph View” on page 160 and “Measure
Result Dialog Box” on page 185.
