CALCulate<Chn>:MATH:FUNCtion
<Mode>
CALCulate<Chn>:MATH:FORMatted:FUNCtion
<Mode>
Defines a simple mathematical trace based on the active trace and its active memory
trace. The first command applies to raw, unformatted trace data (complex data), the
second to formatted trace data. Both methods can be combined.
To apply the trace math, the corresponding mathematical mode must be switched on
using
Note:
Use
CALCulate<Chn>:MATH[:EXPRession]:SDEFine
and/or
CALCulate<Chn>:MATH:FORMatted[:EXPRession]:SDEFine
math traces.
Suffix:
<Chn>
.
Channel number used to identify the active trace
Parameters:
<Mode>
NORMal | ADD | SUBTract | MULTiply | DIVide
NORMal
–
Math. trace = active data trace
ADD
–
Math. trace = data + memory
SUBTract
–
Math. trace = data - memory
MULTiply
–
Math. trace = data * memory
DIVide
–
Math. trace = data / memory
When set to
NORMal
, the corresponding mathematical mode is
turned
OFF
, otherwise it is turned
ON
.
