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

Example: 

SWE:COUN 10

Define the number of sweeps (10) to be measured in single
sweep mode.

INIT:CONT OFF; :INIT; *OPC?

Activate single sweep mode and start a single sweep sequence
in channel no. 1. Wait until the single sweep sequence is com-
plete.

CALC:DATA:NSW? SDAT,3

Query the results of the 8

th

 sweep.
