JGauthier,
You will need to write a dedicated function for that. A wrapper function around the GetIQ functionality should be adequate for performing any triggering on the I/Q data. You could perform video or external triggering with this function. (you didn’t specify trigger type in your message) If external triggering, there is a C++ example showing you how to detect an external trigger event, you would need to then align your capture on the trigger position and collect any additional samples required (with purge disabled to ensure continuity)
The API does not perform any triggering for the user, only provides the facilities for triggering to be performed.
Let me know if you have specific questions as you work through this.
Regards,
Andrew
