PXIe-4139

The PXIe-4139 is a high-precision, system source measure unit (SMU) that features 4-quadrant operation and sources up to 40 W of DC power. This module features analog-to-digital converters that help you perform high-precision measurements with a current resolution of 100 fA or high-speed acquisitions up to 1.8 MS/s. The module can maximize stability and measurement accuracy with SourceAdapt technology, which you can use to tune the transient response to match the characteristics of any load. You can use the PXIe-4139 for applications including manufacturing test, board-level test, and lab characterization with devices such as ICs, power management ICs (PMICs), and RFICs and discrete devices including LEDs and optical transceivers.
