CALCulate:MATH<m>[:EXPRession][:DEFine]
<RemComplExpr>
Defines the equation to be calculated for the selected math waveform as a regular
expression.
Suffix:
<m>
.
1..5
Selects the math waveform.
Parameters:
<RemComplExpr>
String parameter, consisting of the mathematical operation and
the source(s), written in parenthesis. Optionally, the unit can be
included in the string. If no unit is given, the last setting is used.
Example:
CALC:MATH<2>:EXPR:DEF "ADD(CH1,CH2)"
Same command with unit:
CALC:MATH<2>:EXPR:DEF "ADD(CH1,CH2)ín V"
Delete the unit:
CALC:MATH<2>:EXPR:DEF "ADD(CH1,CH2)ín"
Operation
Expression string
