8.2.4.3 Retrieving the results of previous sweeps
The commands CALCulate<Ch>:DATA:NSWeep...? SDATa,
<Trace_Hist_Count> retrieve the results of any sweep within a previously defined
single sweep group. This means that, in single sweep mode, you can first measure a
specified number of sweeps (SENSe<Ch>:SWEep:COUNt <sweeps>) and then read
any of the data traces acquired.
This feature has no equivalent in manual control where always the last data trace is
displayed.
