[:SOURce]:LIST:DIRection <Direc>
Function: This command sets Step Sweep Indirection. Users can select both Forward and
Backward modes: Forward indicates sweep from the first point to the last point in list,
and Backward indicates sweep from the last point to the first point in current list.
Setting format: [:SOURce]:LIST:DIRection UP|DOWN
Query format: [:SOURce]:LIST:DIRection?
Parameter:
<Direc> Discrete data. Step Sweep Indirection is as follows:
UP Start Forward sweep from the first point in list,
DOWN Start Backward sweep from the last point in list.
Example: :LIST:DIRection UP Set Step Sweep Indirection to Forward.
Reset status: UP
Key Entry:
【
Sweep
】
—>[List Sweep]—>[Step Sweep Indirection Forward Backward]
[:SOURce]:LIST:DWELl <Val>{,{Val}}
Function: This command sets the dwell time of each sweep point in current list. If users need to set
different dwell time, it is necessary to enter the corresponding dwell time for each point
in list, i.e. the dwell time parameter value of list sweep points in turn, separated by
commas. If the number of points input by users is less than that of the current list
points, the number of points where the dwell time is not entered uses the current
default.
Setting format: [:SOURce]:LIST:DWELl <val>{,{val}}
Query format: [:SOURce]:LIST:DWELl?
Parameter:
