M Series: Multi Device Synchronization Using LabVIEW

[Chris_VH]

Overview
This example program illustrates how to cleanly configure more than two M Series data acquisition devices to acquire a continuous number of samples.

Description
The code implements one master device and a variable number of slave devices. Thus, it is easily expandable for situations where three or more DAQ devices are required. In addition, a shared timebase and start trigger are used to synchronize the devices. Thus, all devices are synchronized to acquired to within one period of the sampling rate on all channels.

Requirements

• LabVIEW 2012 (or compatible)
• NI DAQmx 12.0 (or compatible)

Steps to Implement or Execute Code

1. Select the physical channel to correspond to where your signal is input on the DAQ device.
2. Enter the minimum and maximum voltage range.

Note:  For better accuracy try to match the input range to the expected voltage level of the measured signal.

3. Set the number of samples to acquire per channel.
4. Set the rate of the acquisition
