Command Syntax
Description
[SOURce]:LIST:REPeat
SWEEp|STEP|CONTinuous
Sets the repeat mode for the current list. The
choices are:
•
SWEEp - Upon triggering, the entire list is
executed from the beginning, then execution
stops.
•
STEP - Upon triggering, the current list point is
executed, then execution stops. The next
trigger executes the next point in the list. The
list’s first point is considered to be the initial
current point, and the point following the list’s
final point.
•
CONTinuous - The entire list repeats
indefinitely.
[SOURce]:LIST:REPeat?
Queries the repeat mode of the current list
[SOURce]:LIST:SEQuence
<m1>,<m2>,<m3>,….,<mn>
Defines a sequence for stepping through the
existing list when [SOURce]:LIST:SEQuence:AUTO
is set to OFF. The points specified in this command
(<m1>,<m2>,<m3>,….,<mn>) are indexes into a
new sub-list, and only points in this sub-list will be
triggered. For example, if one of the indexes
defined with this command is 3, then the third
point in the frequency, dwell, and power lists will
be sequenced.
[SOURce]:LIST:SEQuence:POINts?
Queries the number of points in the sequence list
[SOURce]:LIST:SEQuence:AUTO ON|OFF
Sets list sequence AUTO mode. The choices are:
•
ON The list sequence set with the
[SOURce]:LIST:SEQuence command will not
take effect, so all list points will run when
triggered.
•
OFF The list will run only the points set with
the [SOURce]:LIST:SEQuence command. The
default is ON.
NOTE
: This command is also
used to change the 2400/2500 mode from CW
or Ramp to List mode. Example: LIST: SEQ:
AUTO ON switches to List Mode
