The PXIe-4139 from National Instruments is a high-precision, system-level source measurement unit (SMU) with four-quadrant operation capable of delivering up to 40 W of DC power. The module is equipped with an analog-to-digital converter to ensure a current resolution of 100 fA when performing high-precision measurements and acquisition speeds of up to 1.8 MS/s per channel. The PXIe-4139 uses SourceAdapt technology, which adjusts the transient response to the characteristics of any load, maximizes stability and measurement accuracy, and is suitable for a variety of applications such as manufacturing testing, board level testing and laboratory characterization. This includes testing of integrated circuits (ics), power management integrated circuits (PMIC), radio frequency integrated circuits (RFIC), and discrete devices such as leds and optical transceivers.
