Concurrent Multiple Sample Rates with cDAQ 9178

[GoCougs]

Overview

This example shows how to acquisit and read data in 3 different rates with 3 different devices in the NI cDAQ-9178.

Description

The 9178 has 3 separate timing engines. This is significant because with this device you are able to acquire data at different rates at the same time. This example shows how easy it is to write a program in LabVIEW to accomplish concurrently reading 3 different rates with 3 different devices in the 9178 chasis. This sample cade can be modified to your specific application of the 9178.

Requirements

 Software

•    LabVIEW 2012 or compatible
•    NI-DAQmx 9.5.5 or compatible

 Hardware

•    NI cDAQ-9178

 Steps to Implement or Execute Code

1. In each device tab, choose which modules in the 9178 you will use to acquire data.
2. Set the sample rate and the limit value of input voltage.
3. Run the VI.

Does this code works with 2 different DSA modules working at different rates? Please can someone pot it also in LV8.6 Thx.
