PXIe-5122 Specifications

Definitions

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.

Calibration

External Calibration

External calibration calibrates the VCXO and the voltage reference. All calibration constants are stored in nonvolatile memory.

Self-Calibration

Self-calibration is done on software command. The calibration corrects for gain, offset, frequency response, triggering, and timing adjustment errors for all input ranges.

Software

Driver Software

Driver support for this device was first available in NI-SCOPE3.3.1.

NI-SCOPE is an IVI-compliant driver that allows you to configure, control, and calibrate the PXIe-5122. 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 PXIe-5122 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.

Note 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 PXIe-5122 was first available via InstrumentStudio in NI-SCOPE2018 and via the NI-SCOPE SFP in NI-SCOPE2.7. 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 PXIe-5122. 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 ni.com/support.

Intermodule SMC Synchronization Using NI-TClk for Identical Modules

Specifications are valid under the following conditions:
  • PXI-5122 modules installed in one NI PXI-1042 chassis, or PXIe-5122 modules installed in one PXI Express chassis.
  • All parameters set to identical values for each SMC-based module.
  • Sample clock set to 100 MS/s and all filters disabled.
Note Although you can use NI-TClk to synchronize non-identical modules, these specifications apply only to synchronizing identical modules.
