This command can only be used for
[SENSe<Ch>:]SWEep:COUNt
> 1.
Suffix:
<Chn>
.
Channel number used to identify the active trace
Example: See
CALCulate<Chn>:DATA:NSWeep:FIRSt?
Usage: Query only
CALCulate<Chn>:DATA:NSWeep:FIRSt? <Format>, <FwCount>[, <FwCountEnd>]
Reads the response values of a trace or a consecutive group of traces acquired in sin-
gle sweep mode (
INITiate<Ch>:CONTinuous OFF
).
Tip:
This command can only be used for
[SENSe<Ch>:]SWEep:COUNt
> 1.
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).
<FwCount> Number of first sweep to be read. 1 denotes the first sweep
acquired, 2 denotes the second and so forth. The sweep count
in single sweep mode is defined via
[SENSe<Ch>:]SWEep:
COUNt
.
Range: 1 to sweep count
<FwCountEnd> Number of last sweep to be read. If this parameter is omitted, it
is implicitly set to
<FwCount>
(a single sweep is read).
Range: <FwCount> to sweep count
Return values:
<Data> Response values either in ASCII or block data format, depend-
ing on the current
FORMat[:DATA]
setting.
Example: 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.

Sweeps" , on page 1392.
