Comments • 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 frequency advance triggering. Use
TRIGger:SWEep[:IMMediate] to advance to the next frequency.
– LINK: The next valid start arm advances the sweep or list. Thus, the frequency
change always occurs at the start of
ARM[:STARt][:LAYer[1]]:COUNt repetitions
of the waveform.
– TIMer: The [SOURce:]SWEep:TIME and TRIGger:SWEep:TIMer commands
control the sweep or list frequency advance timing.
– TTLTrg0 through TTLTrg1: The VXIbus TTL trigger lines.
• If TRIGger:SWEep:SOURce is set to TTLTrg<n> and you want to set
ARM:SWEep:SOURce to TTLTrg<n>, both must be set to the same trigger line <n>.

Example Setting the Sweep Advance Trigger Source
TRIG:SWE:SOUR TTLT1 Selects VXIbus trigger line TTLTRG1* as
sweep advance source.
