AXIOMET AX-EL300W60A [25/72] Triggered operation

3.8. Triggered Operation

The triggered operation is mainly used to make the load keep synchronized with other test equipments or

events. This series electronic load provides various triggering modes, which can be applied to the following

occasions:

- Triggering a preset level

Transfers all pending preset levels to the immediate levels. For the presently active mode, the new level

will appear at the input at once if the input is turned on. For the modes which are not presently active, the

preset levels will not take effect at the input until the corresponding mode becomes active.

- Triggering a transient pulse

Gernerates a transient pulse in accordance with the preset transient parameters, when pulsed transient

operation is active.

- Triggering a transient toggle

Switches the input between the transient low level and transient high level in accordance with the preset

transient parameters, when the toggled transient operation is active.

- Triggering a list test

Enables the present list test when the list operation is active.

Three triggering methods are available for remote control: the *TRG and TRIGger commands. The Ex-

ternal trigger input terminal and “Shift”+“0Trigger” key on the front panel of the load can be used to

trigger(can generates a trigger signal to the electronic load).

The load has three triggering modes: BUS, EXTernal, and HOLD.

- The BUS mode: the trigger source is *TRG command.

- The EXTernal mode: Choose the External trigger input terminal or “Shift”+“0Trigger” key on the front

panel as the trigger source. The input signal at the External trigger input terminal is TTL, the falling edge

(signal) is triggered(can generates a trigger signal to the electronic load).

- The HOLD mode: Use the command TRIGger:IMMediate as the trigger source. At this time, all other

triggering methods including *TRG become invalid.

Note:

The command TRIGger:IMMediate can be used in all three triggering modes. The triggering modes can

be selected via the remote command only (TRIGger:SOURce BUS; TRIGger:SOURce EXTernal; TRIG-

ger:SOURce HOLD).

3.9. Input Control

3.9.1. Turn On/Off the Load

The input can be turned on/off by pressing “On/Off” key, or via the remote command (INPUT ON/OFF).

When input is in Off status, press “On/Off” to turn on the input of load and the indicator of “On/Off” is

turned on; When input is in On status, press “On/Off” to turn off the input of load and the indicator of

“On/Off” is turned off; Turning the input on/off does not affect the programmed settings.
