SOURce:MODule:TRIGger:EXTernal:IMMediate

34980A

SOURce:MODule:TRIGger:EXTernal:IMMediate

Syntax

SOURce:MODule:TRIGger:EXTernal:IMMediate <slot>

Description

This command issues an external trigger pulse from the 34951A Isolated DAC Module in the specified slot. Once the external trigger mode is enabled (see SOURce:MODule:TRIGger:OUTPut command), this command issues 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

<slot>

This is a required parameter

Remarks

  • Note that when an external trigger output is issued, all channels on the module configured for an external trigger input will also be triggered (see SOURce:FUNCtion:TRIGger:SOURce EXT command).

  • 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:OUTPut command to enable the trigger output mode on the specified slot.

  • 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.

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

Example

The following command issues an external trigger pulse from the module in slot 4.  

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