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 INI-

Tiate 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.

INIT:CONT OFF

TRIG:SOUR EXT

TRIG:COUNT 10

INIT

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

l 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).

INITiate[1|2][:IMMediate]

INITiate[:IMMediate]:ALL

Change 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.

l 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).
