Overview

Product overview

Key product information and technical features.

The PXIe-4139 integrates one source measure channel into a PXI Express module for PXI-based test systems. Its DC and pulsed current limits are distinct: ±3 A for DC operation and ±10 A for pulsed operation, with a voltage range of ±60 V.

The module supports high-precision measurements with 100 fA current resolution or high-speed acquisitions up to 1.8 MS/s. SourceAdapt technology allows transient response to be tuned to the load characteristics.

  • Single-channel precision source measure architecture.
  • Voltage range from -60 V to 60 V.
  • DC current range of ±3 A and pulsed current range of ±10 A.
  • 100 fA current sensitivity for low-current measurement tasks.
  • SourceAdapt technology for tuning transient response to load characteristics.
  • PXI Express bus connection for integration into PXI-based test systems.

FAQ

Product-specific questions

Product-specific answers based on available technical information.

How many SMU channels does the PXIe-4139 have?

The PXIe-4139 has one source measure channel.

Does the ±10 A rating apply to DC operation?

No. The listed DC current range is -3 A to 3 A. The -10 A to 10 A range applies to pulsed operation. Consult the NI manual for operating limits and pulse conditions.

What does SourceAdapt do on the PXIe-4139?

SourceAdapt allows the module's transient response to be tuned to match load characteristics.

What acquisition performance is identified for this model?

The supplied structured data identifies high-speed acquisitions up to 1.8 MS/s and high-precision measurements with 100 fA current resolution. These describe different measurement capabilities, not necessarily simultaneous performance.

Which NI part numbers are listed for the PXIe-4139?

The listed NI part numbers are 782856-02 and 782856-03. Confirm the required configuration before selecting a part number.
