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 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 490

CALCulate<Chn>:MATH:FUNCtion <Mode>
Defines a simple mathematical relation between the active trace and the active mem-
ory trace to calculate a new mathematical trace and displays the mathematical trace.
Note: This command places some restrictions on the mathematical expression and the
operands. Use
CALCulate<Chn>:MATH[:EXPRession]:SDEFine
to define general
expressions.
Suffix:
<Chn>
.
Channel number used to identify the active trace
