USB-5133 Specifications

    Last Modified: June 15, 2020



    The protection provided by the USB-5133 can be impaired if it is used in a manner not described in this document.

    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.

    The following characteristic specifications 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 in this document are Typical unless otherwise noted.


    Specifications are valid under the following conditions unless otherwise noted:

    • Full bandwidth
    • The Sample Clock is set to full rate.
    • The module is warmed up for 10 minutes at ambient temperature.
    • Self-calibration is completed after warm-up period.
    • Calibration cycle is maintained.

    Driver Software

    Driver support for this device was first available in NI-SCOPE 14.1.

    NI-SCOPE is an IVI-compliant driver that allows you to configure, control, and calibrate the USB-5133. 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 USB-5133 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 USB-5133 was first available via InstrumentStudio in NI-SCOPE 18.1 and via the NI-SCOPE SFP in NI-SCOPE 3.5. 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 USB-5133. MAX is included on the driver media.
