National Instruments PXIe-4147 Source Measure Unit

The PXIe-4147 (Part number: 786888-01) is a Source Measure Unit from National Instruments. Designed specifically for applications with high pin counts, the 4 channels of this device are each equipped with remote four-wire sensing capabilities, allowing for incredibly precise current and voltage readings. The features of the PXIe-4147 are made to improve flexibility and shorten test times- both important considerations when working with source and measurement applications. Boasting a nominal sample rate of (1.8 MS/s)/N, this device shortens the duration of measurements and offers a high resolution performance for projects of all sizes.

Switches, high-speed digital test modules, and other instruments can be easily synchronized to the PXIe-4147 by using a high-speed sequencing engine. NI’s SourceAdapt technology is another valuable addition to SMU toolkit. Built to use a digital control loop rather than an analog control loop, SourceAdapt optimizes the reaction of the PXIe-4147 to any load with minimal transients and maximum stability.

The sinking capacity of the PXIe-4147 is determined by the slot cooling capacity of the chassis. A chassis with a slot cooling capacity of ≥58 W will have a total sinking capacity of 40 W, while a chassis with a slot cooling capacity of <58 W provides a total of 15 W.

When in operation, the PXIe-4147 should be kept in temperatures ranging from 0 °C to 55 °C. When not in use, it can be safely kept in a temperature range spanning from -40 °C to 71 °C. The device weighs 448 g (15.8 oz) with 20 W and 428 g (15.1 oz) with 40 W. It measures dimensions of 2.0 cm × 13.0 cm × 21.6 cm (0.8 in. × 5.1 in. × 8.5 in.).
