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

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:FUNC:TRIG:SOUR EXT,(@4001) !Enable
