:SWEep:SOURce
ARM:SWEep:SOURce <source> selects the source that starts a frequency sweep
or list. The available sources are:
BUS – The Group Execute Trigger (GET) GPIB command or the IEEE-488.2
*TRG common command.
HOLD – Suspend sweep or list arming. Use ARM:SWEep[:IMMediate] to start
the frequency sweep or list.
IMMediate – Immediate sweep or list arming. If the sweep advance trigger
source (
TRIGger:SWEep:SOURce command) is set to TIMer, the first frequency
sweep or list starts when the first start arm is received. For multiple sweeps or
lists, the last frequency point of each sweep or list is output for the same
TRIGger:SWEep:TIMer time as between all other points of the sweep or list.
If
TRIGger:SWEep:SOURce is set to any other source, the frequency sweep or list
starts when the
INITiate:IMMediate command is executed. For multiple sweeps or
lists, a last frequency is output until the next sweep advance trigger is received.
LINK – The next valid start arm starts a sweep or list.
TTLTrg0 through TTLTrg7 – The VXIbus TTL trigger lines.

Comments • If ARM:SWEep:SOURce is set to TTLTrg<n> and you want to set
TRIGger:SWEep:SOURce to TTLTrg<n>, both must be set to the same trigger line
<n>.
