PCI-5922 Specifications

    Last Modified: June 15, 2020


    Warranted specifications describe the performance of a model under stated operating conditions and are covered by the model warranty. Warranted specifications account for measurement uncertainties, temperature drift, and aging. Warranted specifications are ensured by design or verified during production and calibration.

    Characteristics describe values that are relevant to the use of the model under stated operating conditions but are not covered by the model warranty.

    • Typical specifications describe the performance met by a majority of models.
    • Nominal specifications describe an attribute that is based on design, conformance testing, or supplemental testing.
    • Measured specifications describe the measured performance of a representative model.

    Specifications are Typical unless otherwise noted.


    Specifications are valid under the following conditions unless otherwise noted.

    Driver Software

    Driver support for this device was first available in NI-SCOPE 3.0.

    NI-SCOPE is an IVI-compliant driver that allows you to configure, control, and calibrate the PCI-5922. NI-SCOPE provides application programming interfaces for many development environments.

    Application Software

    NI-SCOPE provides programming interfaces, documentation, and examples for the following application development environments:

    • LabVIEW
    • LabWindows™/CVI™
    • Measurement Studio
    • Microsoft Visual C/C++
    • .NET (C# and VB.NET)

    Interactive Soft Front Panel and Configuration

    When you install NI-SCOPE on a 64-bit system, you can monitor, control, and record measurements from the PCI-5922 using InstrumentStudio.

    InstrumentStudio is a software-based front panel application that allows you to perform interactive measurements on several different device types in a single program.


    InstrumentStudio is supported only on 64-bit systems. If you are using a 32-bit system, use the NI-SCOPE–specific soft front panel instead of InstrumentStudio.

    Interactive control of the PCI-5922 was first available via InstrumentStudio in NI-SCOPE 18.1 and via the NI-SCOPE SFP in NI-SCOPE 2.2. InstrumentStudio and the NI-SCOPE SFP are included on the NI-SCOPE media.

    NI Measurement & Automation Explorer (MAX) also provides interactive configuration and test tools for the PCI-5922. MAX is included on the driver media.

    TClk Specifications

    You can use the NI TClk synchronization method and the NI-TClk driver to align the Sample clocks on any number of supported devices, in one or more chassis. For more information about TClk synchronization, refer to the NI-TClk Synchronization Help, which is located within the NI High-Speed Digitizers Help. For other configurations, including multichassis systems, contact NI Technical Support at

    To ensure that the PCI-5922 cools effectively, make sure that the chassis in which it is used has active cooling that provides at least some airflow across the PCI card cage. To maximize airflow and extend the life of the device, leave any adjacent PCI slots empty. Refer to the Maintain Forced-Air Cooling Note to Users included in the kit or available at for important cooling information. The PCI-5922 is intended for indoor use only.
