Comments ∙ Enabling the Trigger Source: The TRIGger:SOURce command only selects the trigger source. The INITiate[:IMMediate] command enables the trigger source.

∙Using the TRIG Command: You can use TRIGger[:IMMediate] to advance the scan when TRIGger:SOURce BUS or TRIGger:SOURce HOLD is selected.

∙Using External Trigger Inputs: With TRIGger:SOURce EXTernal selected, only one switchbox at a time can use the external trigger input at the HP E1300/E1301 Mainframe’s "Event In" port. The trigger input is assigned to the first switchbox requesting the external trigger source (with a TRIGger:SOURce EXTernal command).

∙Assigning External Trigger: A switchbox assigned with

TRIG:SOUR EXT remains assigned to that source until it receives a command to change the source to BUS, HOLD, or IMMediate. When the source is changed, the external trigger source is available to the next switchbox which requests it (with a TRIGger:SOURce EXTernal command). If a switchbox requests an external trigger input already assigned to another switchbox, an error is generated.

∙Using Bus Triggers: To trigger the switchbox with TRIGger:SOURce BUS selected, use the IEEE 488.2 common command *TRG or the HP-IB Group Execute Trigger (GET).

∙"Trig Out" Port Shared by Switchboxes: See the OUTPut command.

∙Related Commands: [ROUTe:]SCAN, TRIGger, ABORt

∙*RST Condition: TRIGger:SOURce IMMediate

Example Scanning Using External Triggers

This example uses external triggering (TRIG:SOUR EXT) to scan channels 00 through 02 of a single-module switchbox. The trigger source to advance the scan is the input to the "Event In" port on an HP E1300A/E1301A mainframe. When INIT is executed, the scan is started and channel 00 is closed. Then each trigger received at the "Event In" port advances the scan to the next channel.

TRIG:SOUR EXT	Sets trigger source to external.
SCAN (@100:102)	Scan channels 00 through 02.
INIT	Begin scan, close channel 00.
trigger externally	Advance scan to next channel.
