Syntax

SOURce:MODule:TRIGger:OUTPut <mode>, <slot>

SOURce:MODule:TRIGger:OUTPut? <slot>

Description

This command disables or enables the trigger output mode on the 34951A Isolated DAC Module in the specified slot. Once the module is properly configured, send the SOURce:MODule:TRIGger:EXTernal:IMMediate command to issue a TTL pulse (one trigger line per module). The primary use of the trigger output mode is to synchronize multiple 34951A modules.

Used With:

  • 34951A Isolated DAC Module

Parameters

Range of Values

Default Value

<mode>

Boolean

{OFF|0|ON|1}

OFF

<slot>

Discrete

{1|2|3|4|5|6|7|8}

This is a required parameter

Remarks

  • To use the trigger output mode, first configure at least one DAC channel in the specified slot for an external trigger (see SOURce:FUNCtion:TRIGger:SOURce EXT command). Then, send the SOURce:MODule:TRIGger:EXTernal:IMMediate command to issue the trigger pulse (also triggers the externally-triggered DAC channel).

  • Sending the SOURce:FUNCtion:TRIGger:IMMediate command to a DAC channel configured for an immediate/manual trigger will trigger the channel, but will not pulse the trigger output line.

  • One signal line is dedicated for both input and output triggering on the 34951A (Pin 25 on the module's D-Sub connector). By default, the trigger line is an input.

  • The trigger output state is stored as part of the instrument state (*SAV command).

  • A Factory Reset (*RST command), Instrument Preset (SYSTem:PRESet command), and Card Reset (SYSTem:CPON command) will turn off the trigger output mode.

Return Format

The query command returns "0" (OFF) or "1" (ON) for the module in the specified slot.

Examples

The following command enables the trigger output mode on the 34951A installed in slot 4. Channel 1 is configured for an external trigger.

SOUR:MOD:TRIG:OUTP ON,4  !Enable trigger output
SOUR:FUNC:TRIG:SOUR EXT,(@4001)  !Enable external trigger
SOUR:MOD:TRIG:EXT:IMM (@4001)  !Pulse trigger output line and trigger DAC channel 1

The following query returns the state of the trigger output mode on the 34951A installed in slot 4.

SOUR:MOD:TRIG:OUTP? 4

Typical Response:  1
