Synchronize a DAQmx Digital Generation with a Triggered AWG Generation and a Scope Acquisition

[AndreaN]

Overview

This example shows how to syhncronize a digital generation using DAQmx with an AWG generation and a Scope acquisition.

Description

The AWG generates a waveform after a digital trigger is detected; the waveform has the first 100 samples set to 0. The AWG exports its sample clock and a marker event on two TTL lines in order to be used by the DAQ board for syncronization purposes.

The DAQ board generates a pattern with the first 100 samples set to 1, so it's easy to verify on the graph that the two generated signals are synchronized.

The Scope acquisition is also syncronized with the AWG generation using NI TClk technology.
