I created software, current pulse sourcing & measure voltage (digitizing mode) , 150 usec pulse width for VCSEL device using 2461.
In now, I need a some trigger signal in pulse width timing for external instrument measurement (optical power).
Is there any solution for trigger-out signal generate at that system?

Hi Gibbs,

First configure a digital line to give a trigger out when it receives the NOTIFY stimulus.
From the trigger blocks, you can add an entry to use the Notify event to cause the digital IO trigger. 
  1. ​​​​​​​--setup digital output to strobe when NOTIFY2 event occurs
  2. digio.line[1].mode = digio.MODE_TRIGGER_OUT
  3. trigger.digout[1].pulsewidth = 10e-6
  4. trigger.digout[1].stimulus   = trigger.EVENT_NOTIFY2
  5.  
  6. trigger.model.setblock(blockNumber, trigger.BLOCK_NOTIFY, trigger.EVENT_NOTIFY2)  -- strobe the digital output
