PC-Based Measurement and Control Systems

PC-based measurement and control systems provide electrical and physical measurement capabilities for engineers who need a customizable and accurate, yet cost-effective way of conducting benchtop measurements.

What Are PC-Based Measurement and Control Systems?

In a PC-based measurement and control system, NI hardware products are connected to your PC or laptop through USB or Ethernet. This kind of system has two main architectures: directly connect a multifunction I/O device to your PC or connect a CompactDAQ Chassis to your PC, and populate this chassis with conditioned I/O modules. CompactDAQ provides the most customizable solution with direct sensor connectivity.

Quickly Capture and Explore, and Then Customize Your Measurement System

Save time with quick, clear access to your measurements using DAQExpress™ companion software that is shipped with all PC-based DAQ hardware. With DAQExpress, you can quickly configure your measurement across multiple channels and instantly view, explore, and save data. Build on your measurement system with LabVIEW to automate your measurements, perform advanced analysis, and integrate third-party instruments.

Accurate Precisely Timed Data You Can Trust

The superior analog design quality of NI measurement products and proprietary technology, such as the STC3 timing chip, delivers the accuracy you need to trust your data. CompactDAQ provides a modular, signal-conditioned architecture that gives you direct sensor connectivity, no matter your application requirements. Some CompactDAQ Chassis also support Time Sensitive Networking (TSN), an update to the Ethernet standard that provides synchronization and data transfer between multiple chassis, so there’s no need for separate timing and triggering wires.

Advanced Driver Functionality for Greater Productivity and Performance

NI-DAQmx driver software goes far beyond a basic DAQ driver to deliver increased productivity and performance in DAQ and control application development. NI-DAQmx allows you to specify every aspect of your DAQ system (including NI signal conditioning devices), from device configuration and timing setup to low-level OS and device control, all with one straightforward API. The NI-DAQmx driver is compatible with all NI DAQ hardware, so the same code can reference different devices with no code changes. NI-DAQmx works with LabVIEW, DAQExpress, LabWindows™/CVI, C/C++, Visual Basic, Visual Basic .NET, and C#.

World-Class Support and Full Documentation

Ensure you have specified and installed your system to meet your application’s precise requirements with NI’s detailed and complete product documentation. Then minimize troubleshooting time with help from a vibrant and growing community on the NI forums, direct communication with local NI engineers, and online and instructor-led training. Finally, keep measurements accurate with NIST-traceable calibration and factory calibration services.
