PC-based measurement and control systems provide engineers with electrical and physical measurement capabilities, enabling them to perform benchtop measurements in a customizable, accurate, and cost-effective manner.

What are PC-based Measurement and Control Systems? In PC-based measurement and control systems, NI hardware products connect to a PC or laptop via USB or Ethernet. These systems feature two main architectures: connecting a multifunction I/O device directly to a PC, or connecting a CompactDAQ chassis to a PC and inserting conditioned I/O modules into that chassis. CompactDAQ offers solutions with excellent customizability for direct sensor connection.

Key Features of PC-based Measurement and Control Systems

Quickly Capture and Explore Data, and Customize Your Measurement System All PC-based DAQ hardware comes with DAQExpress™ companion software, which allows you to quickly and smoothly access measurement results, saving you time. With DAQExpress, you can quickly configure multi-channel measurements and instantly view, browse, and save data. Built upon your measurement system, you can use LabVIEW to automate measurements, perform advanced analysis, and integrate third-party instruments.

Trustworthy, Precisely Timed Data NI measurement products and patented technologies (such as the STC3 timing chip) provide excellent quality and precision for analog designs, allowing you to fully trust your measurement data. CompactDAQ offers a modular signal conditioning architecture that allows direct sensor connection regardless of your application needs. Some CompactDAQ chassis also support Time-Sensitive Networking (TSN), which is an updated version of the Ethernet standard, providing synchronization and data transfer between multiple chassis, eliminating the need for separate timing and trigger lines.

Use Advanced Driver Features to Improve Productivity and Performance NI-DAQmx driver software offers capabilities far beyond basic data acquisition drivers, providing greater efficiency and performance for data acquisition and control application development. NI-DAQmx allows you, through a single, simple API, to configure all aspects of your DAQ system (including NI signal conditioning devices), from device configuration and timing settings to low-level OS and device control. The NI-DAQmx driver is compatible with all NI DAQ hardware, so the same code can reference different devices without any code changes. NI-DAQmx can be used with LabVIEW, DAQExpress, LabWindows™/CVI, C/C++, Visual Basic, Visual Basic .NET, and C#.
