The National Instruments PXIe-4162, identified by part number 785680-02, is a high-performance Source Measure Unit (SMU) designed for precision measurements in a variety of applications. This 12-channel device features a remarkable current sensitivity of 10 pA and a DC voltage range of ±24 V, enabling it to measure voltage and current simultaneously with exceptional accuracy. Power requirements for the device vary based on the chassis cooling capacity; it typically draws 1 A at +3.3 V and 3 A at +12 V for chassis with a slot cooling capacity of 38 W, while at least 1 A at +3.3 V and 4.5 A at +12 V is required for chassis with capacities of ≥58 W.

The PXIe-4162 is built to endure operating conditions, capable of withstanding a peak operating shock of 30 g over an 11 ms pulse and randomly vibrating between 5 Hz to 500 Hz. It is designed for use in environments with temperatures ranging from 0 °C to 40 °C, extending to 0 °C to 55 °C when paired with appropriately cooled chassis. For storage, the unit can endure temperatures between -40 °C and 71 °C. Compact in design, the PXIe-4162 measures 2.0 cm × 13.0 cm × 21.6 cm (0.8 in. × 5.1 in. × 8.5 in.) and weighs just 394 g (13.9 oz). This reliable and versatile instrument comes with a three-year warranty, ensuring consistent performance for demanding testing environments.
