If you change step size then the number of points will be changed to span/step and a Parameter Bumped execution error is reported. If span or points are changed then STEP= SPAN/POINTS. The step sweep command creates a coupling with sweeptime also. If points is changed through this coupling and DWELl:AUTO is ON and TIME:AUTO is ON then dwell is changed to SWEEPTIME/POINTS. Span is normally an independent variable but is changed to STEP x POINTS if both of these parameters are changed in the same message. *RST value is StopMax-StartMin/lO.

SWEep:TIME <num>[time suffix] lMAXimumlMINimum

SWEep:TIME? [MAXimumlMINimum]

Sets and queries the current sweep time. The dwell time can be coupled to sweep time if SWE : DWEL : AUTO is ON. The dwell time is then governed by the equation DWELl = SWEEPTIME/POINTS. Changing either sweep time or the number of points causes DWELl to be recalculated but does not cause an error. If you attempt to change the dwelltimethen :AUTOis set to OFF.IfDWELl:AUTOis OFF then sweep time is independent of the dwell time and the number of points. *RST value is MIN.

SWEep:TIME:AUTO ONlOFFlllO

SWEep:TIME:AUTO?

Sets and queries the automatic sweep time switch.

ON

The value of the sweep time is automatically to

 

minimum.

OFF

Attempting to set a sweep time faster than allowed

 

in the AUTO mode causes this switch to change to

 

AUTO ON evenifit was previously in the AUTO OFF

 

mode.

*RST state is ON.

a SWEep:TIME:LLIMit <num>[time suffix]lMAXimumlMINimum

SWEep:TIME:LLIMit.7 [MAXimumlMINimum]

Sets and queries the lower sweep time limit. This value specifies the fastest sweep time that you wants the synthesizer to allow either on input or when calculated internally when in AUTO ON mode. This value must be greater than 10 ms. *RST value is 10 ms.

a SWEep:TRIGger:SOURce IMMediatelBUSlEXTernal

SWEep:TRIGger:SOURce?

Sets and queries the stepped sweep point-to-point trigger source.

This only applies when SWEep:GEN is set to STEPped.
