Operating Manual 1145.1084.12 – 30 616
<Forward_Count>
Number of first sweep to be read. 1 denotes the first sweep acquired, 2
denotes the second and so forth.
Range [def. unit]
1 to sweep count defined via [SENSe<Ch>:]SWEep:COUNt [–]
*RST value
–
<Forward_Count_End>
Number of last sweep to be read. If this parameter is omitted, it is
implicitly set to <Forward_Count> (a single sweep is read).
Range [def. unit]
<Forward_Count> to sweep count defined via
[SENSe<Ch>:]SWEep:COUNt [–]
*RST value

SCPI, Command Types
Device-specific, query only
Example (see also Sweep
History):
SWE:COUN 10
Define the number of sweeps (10) to be measured in single sweep
mode.
INIT:CONT OFF; :INIT;
Activate single sweep mode and start a single sweep sequence 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.
CALCulate<Chn>:DATA:NSWeep[:LAST]? SDATa, <Reverse_Count>
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 during the single sweep cycle.
Ensure that the single sweep is terminated before using this command, otherwise the results of the
trace count will be unpredictable. See example below. Alternatively, use the
CALCulate<Chn>:DATA:NSWeep:FIRSt? command.
<Chn>
Channel number used to identify the active trace.
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). Wave quantities are returned as
voltages.
<Reverse_Count>
Number of sweep to be read. 1 denotes the last sweep acquired, 2 denotes
the second-last and so forth.
Range [def. unit]
1 to sweep count defined via [SENSe<Ch>:]SWEep:COUNt [–]
