Define the number of sweeps (10) to be measured in single
sweep mode.
INIT:CONT OFF; :INIT;

in channel no. 1. No synchronization is necessary.
if (CALC:DATA:NSW:COUN? > 4)
CALC:DATA:NSW:FIRS? SDAT, 5
Wait until 5 sweeps have been measured, then query the results
of the 5
th sweep.
See also "Retrieving the results of previous sweeps"
on page 1073.
Usage: Query only
CALCulate<Chn>:DATA:NSWeep[:LAST]? <Format>, <RvCount>
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 dur-
ing the single sweep cycle.
Tip:
●
This command can only be used for
[SENSe<Ch>:]SWEep:COUNt
> 1.
●
Ensure that the single sweep is terminated before using this command, otherwise
the results of the trace count will be unpredictable (see example below). Alterna-
tively, use the
CALCulate<Chn>:DATA:NSWeep:FIRSt?
command.
Suffix:
<Chn>
.
Channel number used to identify the active trace
Query parameters:
<Format> SDATa
Read unformatted sweep data (fixed parameter): Returns the
real and imaginary part of each measurement point (2 values
per trace point, irrespective of the selected trace format).
<RvCount> Number of sweep to be read. 1 denotes the last sweep acquired,
2 denotes the second-last and so forth.
Range:
1 to sweep count defined via
[SENSe<Ch>:]SWEep:COUNt
