[:STARt]:LAYer2:SOURce
ARM[:STARt]:LAYer2:SOURce <source> selects the source that will start
waveform output. The available sources are:
BUS – The Group Execute Trigger (GET) GPIB command or the IEEE-488.2
*TRG common command.
ECLTrg0 and ECLTrg1 – The VXIbus ECL trigger lines.
EXTernal – The Agilent E1445A’s front panel “Start Arm In” BNC connector.
HOLD – Suspend arming. Use the ARM[:STARt]:LAYer2[:IMMediate] command
to start the waveform.
IMMediate – Immediate arming. An arm is internally generated two to three
reference oscillator cycles after the start trigger sequence enters the
wait-for-arm state.
TTLTrg0 through TTLTrg7 – The VXIbus TTL trigger lines.
