Hi Arc,
It sounds like you currently have your application configured for immediate triggering. In this mode the acquisition begins immediately after being configured by the driver software. There are a few options that I think may work in your application:
1. Edge Triggering - occurs when a signal crosses a trigger threshold that you specify. You can
specify the slope as either positive (on the rising edge) or negative (on the
falling edge) to the trigger.
2. Digital Triggering - occurs on either a rising edge or falling edge of an external digital signal.
3. Triggering with Trigger Delay - the amount of time that elapses between when a trigger occurs and when the
digitizer actually triggers.
Refer to the High-Speed Digitizer help
here for more information about the trigger options available.
