Retrieve All Trigger Instances from Waveform

[Andrew_B]

Overview

Demonstrate the method to detect the first level-crossing location in a waveform.

Description

This VI demonstrates retrieving all trigger instances from a waveform. The inputs are a path to a waveform file (.lvm) and configuration for the Basic Level Trigger Detection VI. The output is an array of trigger indexes in the waveform. Attached are the VI and a sample waveform file (.lvm). This VI can be easily extended to:

1. analyze an acquired IO signal (such as from DAQmx Read)
2. determine trigger times (using waveform components t0 and dt)
3. analyze multiple signals (using the waveforms output of Read Waveforms from File

Requirements

• LabVIEW 2012 (or compatible)

Steps to Implement or Execute Code

1. Download the attached folder to your computer
2. Open the VI " Retrieve All Trigger Instances from Waveform 2012 NIVerified.vi".
3. Run the VI. 
4. Select the Example Wave form (Example Wave form.lvm).
