PXI-5154 Specifications

    Last Modified: August 15, 2019


    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.

    • All filter settings.
    • All impedance selections.
    • Sample clock set to 1 GS/s.
    • Real-Time Interleaved Sampling (TIS) mode provides a 2 GS/s real-time sample rate for a single channel.
    • The module is warmed up for 15 minutes at ambient temperature.
    • Self-calibration is completed after warm-up period.
    • Calibration cycle is maintained.
    • The PXI/PCI chassis fan speed is set to HIGH, the foam fan filters are removed if present, and the empty slots contain slot blockers and filler panels. For more information about cooling, refer to the Maintain Forced-Air Cooling Note to Users.

    If the module has been in use, it may exceed safe handling temperatures and cause burns. Allow the module to cool before removing it from the chassis.

    Self-calibration is done on software command. The calibration corrects for gain, offset, triggering, and timing errors for all input ranges, excluding External Trigger input channel.

    Driver Software

    Driver support for this device was first available in NI-SCOPE 3.5.

    NI-SCOPE is an IVI-compliant driver that allows you to configure, control, and calibrate the PXI-5154. 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 PXI-5154 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 PXI-5154 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 PXI-5154. 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

    Intermodule SMC Synchronization Using NI-TClk for Identical Modules

    Synchronization specifications are valid under the following conditions:

    • All modules are installed in one NI PXI-1042 chassis
    • The NI-TClk driver is used to align the Sample clocks of each module.
    • All parameters are set to identical values for each module.
    • Modules are synchronized without using an external Sample clock.
    • Sample clock set to 1 GS/s and all filters are disabled.

    Although you can use NI-TClk to synchronize non-identical SMC-based modules, these specifications apply only to synchronizing identical modules.
