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.
