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 dis-
played.
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, mathemati-
cal trace displayed).
Manual operation: See "Data / <Mem>, Data - <Mem>" on page 488
CALCulate<Chn>:MATH:MEMorize
Copies the current state of the active data trace to a memory trace. If a mathematical
trace is active, the data trace associated with the mathematical trace is copied. The
memory trace is named
Mem<n>[<Data_Trace>]
where
<n>
counts all data and
memory traces in the active recall set in chronological order, and
<Data_Trace>
is
the name of the associated (copied) data trace.
The exact function of the command depends on the number of memory traces associ-
ated to the active data trace:
●
If no memory trace is associated to the active trace, a new memory trace is gener-
ated.
●
If several memory traces are associated to the active trace, the current measure-
ment data overwrites the last generated or changed memory trace.
Note: To copy a trace to the memory without overwriting an existing memory trace or
define a memory trace name, use
TRACe:COPY
<MemTraceName>,<DataTraceName>
. To copy an active mathematical trace use
TRACe:COPY:MATH <MemTraceName>,<DataTraceName>
Suffix:
<Chn>
.
Channel number used to identify the active trace
