:SWEep:DWELl
[SOURce]:SWEep:DWELl <value>
[SOURce]:SWEep:DWELl?
This command sets the dwell time for the current step sweep points. Dwell time is used when
IMMediate is the trigger source. The dwell time is the amount of time the sweep is guaranteed to
pause after setting the frequency and/or power for the current point.
The setting enabled by this command is not affected by signal generator power- on, preset, or
*RST.
The variable <value> is expressed in units of seconds (default: 1000
P
S).
:SWEep:DELay
[SOURce]:SWEep:DELay <value>
[SOURce]:SWEep:DELay?
This command sets the off time for the current step sweep points. Off time is used when IMMediate is
the trigger source. The off time is the amount of time the sweep is guaranteed to pause after setting
the frequency and/or power for the current point.
The setting enabled by this command is not affected by signal generator power- on, preset, or
*RST.
The variable <value> is expressed in units of seconds (default: 300
P
S).
