CALCulate<Chn>:MATH:FUNCtion
<Mode>
Defines a simple mathematical relation between the active trace and the active memory
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
expressions.
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
*RST:
NORMal
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 displayed.
CALC:MATH:FUNC DIV
Define a mathematical trace, dividing the data trace by the stored
memory trace. The mathematical trace is displayed instead of the
active data trace.
CALC:MATH:STAT?
The response is 1 (mathematical mode switched on, mathematical
trace displayed).
