Increase the number of points to 401.

 

 


[SENSe<Ch>:]SEGMent<Seg>:SWEep:TIME <Sweep Time>

Sets the duration of the sweep in sweep segment no. <Seg> (Segment Sweep Time). At the same time, the command activates separate sweep time setting in all sweep segments ([SENSe<Ch>:]SEGMent<Seg>:SWEep:TIME:CONTrol ON).

<Ch>

Channel number.

 

<Seg>

Sweep segment number.

 

<Sweep Time>

Segment sweep time.

Range [def. unit]

The minimum duration depends on the other channel settings, in particular on the number of points ([SENSe<Ch>:]SEGMent<Seg>:SWEep:POINts), the IF bandwidth (BWID) and the delay for each partial measurement ([SENSe<Ch>:]SEGMent<Seg>:SWEep:DWELl). The maximum is 1000 s. [s] Changing the duration leaves the number of points unchanged but directly affects the delay.

*RST value

MIN, depending on the channel settings. This default value corresponds to automatic sweep time setting in manual control.

 

SCPI, Command Types

Device-specific, command or query

 

Example:

SEGM:ADD

Create a new sweep segment no. 1 in channel no. 1.

SEGM:SWE:TIME 0.1

Increase the segment sweep time to 0.1 s.

SEGM:SWE:TIME:SUM?

Query the total duration of the segmented sweep. The response is 0.1, because there is only one sweep segment.

 

 


[SENSe<Ch>:]SEGMent<Seg>:SWEep:TIME:CONTrol <Boolean>

Qualifies whether or not the Segment Sweep Time can be set independently for each sweep segment.

<Ch>

Channel number.

 

<Seg>

Sweep segment number. This suffix is ignored; the command controls the whole segmented sweep.

 

<Boolean>

ON: The time can be set independently for each sweep segment.
OFF: The time in all sweep segments is equal to the sweep time for unsegmented sweeps set via [SENSe<Ch>:]SWEep:TIME.   

*RST value

OFF. The parameter is automatically switched to ON when a segment sweep time is entered using [SENSe<Ch>:]SEGMent<Seg>:SWEep:TIME or if the channel settings in a sweep segment require a sweep time larger than the unsegmented sweep time.

 

SCPI, Command Types

Device-specific, command or query

 

Example:

SEGM:ADD

Create a new sweep segment no. 1 in channel no. 1.

SEGM:SWE:TIME 0.1

Increase the segment sweep time to 0.1 s.

SEGM:SWE:TIME:CONT OFF

Couple the sweep times in all segments and reset the sweep time in segment no. 1 to the initial value.  

 

 


[SENSe<Ch>:]SEGMent<Seg>:SWEep:TIME:SUM?

Returns the total duration of the segmented sweep, calculated as the sum of the sweep times of the individual segments ([SENSe<Ch>:]SEGMent<Seg>:SWEep:TIME).   

<Ch>

Channel number.

 

<Seg>

Sweep segment number. This suffix is ignored; the command returns the sum of all segments.

 

<Sweep Time>

Segment sweep time.
