Requirements: View

This LabVIEW example shows how to perform a simple analog level trigger with pre-trigger samples in software using DAQmx.

Triggering is especially important in measurements such as an impact test where you are only interested in the data around the impact time.

This is for programmers using the USB-9233 (which does not have hardware analog triggering) who want to perform an impact test.

Great start to a tap test VI
I used this as the core to a very nice little tap test VI. It is a very interesting approach to a tough problem of acquiring pretrigger samples. Really nice VI
