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 Data Flow diagram):
FDATa
Formatted trace data, according to the selected trace format (CALCulate<Chn>:FORMat
). 1 value per trace point for
Cartesian diagrams, 2 values for polar diagrams.
SDATa
Unformatted trace data: Real and imaginary part of each measurement point. 2 values per trace point irrespective of the
se
lected trace format. The trace mathematics is not taken into account.
MDATa
Unformatted trace data (see SDATa
) after evaluation of the trace mathematics.
The following parameters denote the error terms generated during a calibration:

Use the generalized command [SENSe<Ch>:]CORRection:COLLect:CDATa to read or write error
terms for arbitrary analyzer ports.
CALCulate<Chn>:DATA:NSWeep? SDATa, <Trace_Hist_Count>
Reads the response values of a trace acquired in single sweep mode (INITiate<Ch>:CONTinuous
OFF). The trace can be any of the traces acquired during the single sweep cycle.
<Chn>
Channel number used to identify the active trace.
SDATa
Read unformatted sweep data (fixed parameter): Returns the real and
imaginary part of each measurement point (2 values per trace point
