●
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 345
