2400 Series SourceMeter

User’s Manual Triggering 11-17

Output triggers

The SourceMeter can be programmed to output a trigger (via rear panel Trigger

Link connector) after various trigger model operations. An output trigger is used to

trigger another instrument to perform an operation. The default is no output trig-

gers. See “Trigger link” later in this section for more information.

Trigger layer output triggers — The SourceMeter can be programmed to output

a trigger after each action of the SDM cycle (Source, Delay and Measure). Output

triggers are controlled with the TRIGger:OUTPut command.

For example, to output a trigger after the Measure Action, the following command

must be sent:

TRIGger:OUTPut SENSe

The above command disables output triggers for the Source and Delay Actions

since their parameter names (SOURce and DELay) are not included in the param-

eter list.

When used with a scanner, an output trigger after each measurement can signal

the scanner to select the next channel in the scan.

Arm layer output trigger — As shown in Figure 11-3, the SourceMeter can be

programmed to output a trigger when operation leaves the Arm Layer and enters

the Trigger Layer, or after operation leaves the Trigger Layer and enters back into

the Arm Layer. This output trigger is typically sent to another instrument to signal

the end of a scan or sweep. The ARM:OUTPut command is used to control these

output triggers. The TENTer parameter enables the trigger on entering the Trigger

Layer, the TEXit parameter enables the trigger on exiting the Trigger Layer, and

the NONE parameter disables both output

triggers.

GPIB defaults

The GPIB defaults are listed as follows. They are also denoted in Figure 11-3 by

the “✛” symbol.

• Arm-In Event = Immediate

• Trigger-In Source = Immediate

• Arm Count = 1

• Trigger Count = 1

• Trigger Delay = 0.0 sec

• Delay Action = 0.001 sec

• Enabled event detector = Source Event Detector (Delay and Measure

detection disabled)

• Enabled output triggers = None

• Event detection bypasses = Acceptor (both layers)
