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.
