Example:
*RST; SWE:POIN 20
Create a trace with 20 sweep points, making the created trace
the active trace of channel 1 (omitted optional mnemonic
SENSe1).
CALC:DATA? FDAT
Query the 20 response values of the created trace. In the FDATa
setting, 20 comma-separated ASCII values are returned.
CALC:DATA:STIM?
Query the 20 stimulus values of the created trace. 20 comma-
separated ASCII values are returned.
CALC2:PAR:SDEF 'Trc2', 'S11'
Create a second trace in a new channel no. 2. The second trace
does not become the active trace and is not displayed.
CALC:DATA:TRAC? 'Trc2', FDAT
Query the response values of the second (non-active) trace. 20
comma-separated ASCII values are returned.
CALC:DATA:ALL? FDAT
Query the response values of all traces. 40 comma-separated
ASCII values are returned.
Example:
Writing memory traces
*RST; SWE:POIN 3
Create a data trace 'Trc1' with 3 sweep points, making the cre-
ated trace the active trace of channel 1 (omitted optional mne-
monic SENSe1).
TRAC:COPY 'MemTrc1','Trc1'; :CALC:PAR:SEL
'MemTrc1'
Copy the data trace to a memory trace and select the memory
trace as an active trace.
CALC:DATA SDAT, 1,2, 3,4, 5,6
Write numbers (1,2), (3,4), (5,6) to the memory trace.
CALC:DATA? SDAT
Query the memory trace. The response is 1,2,3,4,5,6.
FORM REAL,32
Change the data format to 4-byte block data.
CALC:DATA SDAT, #224123456789012345678901234
Write 24 bytes (= 4 * 2 * 3 bytes) of data to the memory trace.
The following parameters are related to trace data (see also diagram in Chapter 9.1.5,
"Data flow", on page 190):
Table 11-5: Data format identifiers used in the CALCulate:DATA... commands
FDATa Formatted trace data, according to the selected trace format
(CALCulate<Chn>:FORMat). One value per trace point for Cartesian diagrams,
two values for polar diagrams.
[Data access point 6]
SDATa Unformatted trace data: real and imaginary part of each measurement point. Two
values per trace point irrespective of the selected trace format. The trace mathe-
matics is not taken into account.
[Data access point 4]
