Analog Input - Synchronization (Sample Clock, Reference Clock, Start Trigger)

Overview

The example gives the different options to synchronize DAQ cards using DAQmx

 

Description

This example is intended to show low level synchronization of various devices. DSA, S Series, X Series, and SC Express devices support including channels from multiple devices in a single task. DAQmx automatically synchronizes the devices in such a task.  See the DAQmx Help>>Device Considerations>>Multi Device Tasks section for further details. 

*Note: The example was tested succesfully with LabVIEW 2013, and a PCIe-6363 connected with a NI PCIe-6351 using a RTSI cable which was created before in NI-MAX.

 

Requirements

Software

  • LabVIEW 2013 (or compatible)
  • DAQmx 9.7.5 (or compatible)

 Hardware

Two or more NI DAQ devices as DSA, S Series, X Series, and SC Express devices

 

Steps to Implement or Execute Code

  1. Download both attach VI´s and paste them in the same carpet.
  2. Connect two DAQ cards, f.e. the PCIe-6363 and the PCIe-6351 to the computer.
  3. Use a RSTI cable to connect both cards.
  4. Ensure the cards are working with NI-MAX.
  5. Select the cards as Master and Slave.
  6. Select the Synchronization type (Read the **Note).
  7. Set timing settings correctly.
  8. Select the type of synchronization you want to execute (Read Note 2 and Note 3).
