CALCulate:MATH...
The
CALCulate:MATH...
commands permit processing of measured data in numeri-
cal expression format. The operators are +, -, *, / and use of constants and data arrays
are permitted.

CALCulate<Chn>:MATH[:EXPRession]:SDEFine <Expression>
CALCulate<Chn>:MATH:FORMatted[:EXPRession]:SDEFine <Expression>
Defines a mathematical trace for the active trace, using a string expression.
●
The expression in the first command refers to raw, unformatted trace data (complex
data). In order to apply it,
CALCulate<Chn>:MATH:FUNCtion
must be set to
NORMal
and
CALCulate<Chn>:MATH:STATe
must be set to
ON
.
●
The expression in the second command refers to formatted trace data. In order to
apply it,
CALCulate<Chn>:MATH:FORMatted:FUNCtion
must be set to
NORMal
and
CALCulate<Chn>:MATH:FORMatted:STATe
must be set to
ON
.
Trace math for unformatted and formatted trace data can be used at the same time.
Suffix:
<Chn>
.
Channel number used to identify the active trace
Parameters:
<Expression> Operands, operators and functions; see table below.
Example: *RST; :CALC:MATH:MEM
Copy the current state of the default trace
'Trc1'
to a memory
trace named
'Mem2[Trc1]'
. The memory trace is not dis-
played.
CALC:MATH:SDEF 'Trc1 / Mem2[Trc1]'
Define a mathematical trace, dividing the raw complex data
trace by the stored memory trace. The mathematical trace is not
displayed.
CALC:MATH:STAT ON
Display the mathematical trace instead of the active data trace.
Manual operation: See "Expression builder" on page 331
