Frequency Counters

Frequency Counters measure frequency, period, time interval, pulse width, duty cycle, frequency ratio, phase, and more. Frequency counter products include options that are compatible with Astronics/Racal VXI-2461C, which can be used for automated test aerospace and defense applications.

    Platform Modules

    Platform modules integrate with modular hardware platforms that allow you to combine different types of modules in a custom system that leverages shared platform features. NI offers three hardware platforms—CompactDAQ, CompactRIO, and PXI—though all platforms may not be represented in this category.

  • Performs counter timer tasks such as encoder position measurement, event counting, period measurement, pulse measurement and generation, and frequency measurement in PXI systems.

    Feature Highlights:

    • Platform: PXI
    • Bus: PXI, PXI Express
  • Stand-Alone or Computer-Based Devices

    Stand-alone or computer-based devices either integrate with standard desktop and laptop computers or allow you to use them without the need for other modular hardware.

  • Performs counter timer tasks such as encoder position measurement, event counting, period measurement, pulse measurement and generation, and frequency measurement in desktop systems.

    Feature Highlights:

    • Bus: PCI, PCI Express
