INITiate Subsystem

The INITiate subsystem controls how the instrument moves from the "idle" state to the "wait for trigger" state. You may do this one channel at a time, or for both channels with the "ALL" keyword.

Example

This program uses INITiate[1|2][:IMMediate] with TRIGger[1|2]:SOURce and TRIGger[1|2]:COUNt. The TRIG:SOUR EXT command configures the channel for external triggering, and TRIG:COUNT sets the trigger count to 10. The INITiate command places the instrument in the "wait-for-trigger" state. The trigger will occur when the rear-panel Ext Trig line is pulsed (high by default). The channel will return to idle after the trigger count of 10 has been satisfied. Another INIT command would then be necessary to restart the acceptance of triggers from the external trigger input line.

INITiate[1|2]:CONTinuous {ON|1|OFF|0}
INITiate[1|2]:CONTinuous?

INITiate:CONTinuous:ALL {ON|1|OFF|0}

Specifies whether the trigger system for one or both channels (ALL) always returns to the "wait-for-trigger" state (ON) or remains in the "idle" state (OFF), ignoring triggers until INITiate:IMMediate is issued.

Parameter	Typical Return
{ON\|1\|OFF\|0}, default ON	0 (OFF) or 1 (ON)
Configure both channels for continuous trigger: INIT:CONT:ALL ON

Once the channel is triggered, it leaves the wait-for-trigger state and enters the "action-in-progress" state (for example, burst-in-progress or sweep-in-progress). The action-in-progress state can be lengthy, and during this state triggers are ignored (will not count against number of triggers specified by TRIGger[1|2]:COUNt).
With INIT:CONT ON, the trigger count is meaningless because there is no way to distinguish the completion of one trigger count from the first trigger of the next trigger count. If you need counted triggers, you must set INIT:CONT OFF.

INITiate[1|2][:IMMediate]

INITiate[:IMMediate]:ALL

Changes state of triggering system for both channels (ALL) from "idle" to "wait-for-trigger" for the number of triggers specified by TRIGger[1|2]:COUNt.

Once the channel is triggered, it leaves the wait-for-trigger state and enters the "action-in-progress" state (for example, burst-in-progress or sweep-in-progress). The action-in-progress state can be lengthy, and during this state triggers are ignored (will not count against number of triggers specified by TRIGger[1|2]:COUNt).

Parameter	Typical Return
(none)	(none)
Change both channels to the wait-for-trigger state: INIT:IMM:ALL

The trigger system is armed by INITiate[:IMMediate]. Once the trigger count is satisfied, the trigger system returns to idle state and ignores further triggers. The triggered function will be left in whatever state is achieved with the count of triggers. Rearming the trigger system with another INITiate[:IMMediate] allows further triggers to apply.
Use ABORt to return instrument to idle.
If the specified channel has INIT:CONT set ON, INITiate[1|2]:IMMediate and INIT[:IMMediate]:ALL have no effect on the trigger system and error -213 will be generated.
