Send a signal to a soundcard after a fixed delay from an analog trigger using labview 7 express

We are trying to use data from an analog input to trigger a "go" signal that is generated by the sound card. The signal must be delayed 500ms before starting triggring the sound card. We are using Labview 7 Express.

Hi tj33,

 

Thank you for posting to the NI forums.  I need some more information about your system before making any suggestions regarding the design and implementation of this application.

 

  1. What DAQ device are you using?
  2. What DAQ driver are you using (DAQmx or Traditional DAQ)?
  3. What is the longest duration between the analog trigger and the digital output?  This will determine whether you should be using hardware timing or software timing.

Please post back with this info, and I’ll get back to you with some suggestions.  Thanks!
