National Instruments 785680-01

The National Instruments 785680-01 PXIe-4162 Source Measure Unit (SMU) is a sophisticated instrument designed for precise voltage and current measurements with a remarkable current sensitivity of 100 pA. Featuring 12 channels, this instrument supports a DC voltage range of ±24 V, allowing for simultaneous measurements that enhance accuracy and operational efficiency. Connectivity is optimized through custom 62-position D-SUB female connectors located on the front panel, providing flexibility in interfacing with various external devices. The 785680-01 includes four distinct input trigger types—Start, Source, Measure, and Sequence Advance—facilitating easy synchronization of operations with external systems. The operating temperature range for this device is specified as 0 °C to 40 °C, though it can operate up to 55 °C when installed in a chassis with a slot cooling capacity of 58 W or greater. For storage, the unit can withstand a broader temperature range of -40 °C to 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 only 394 g (13.9 oz). The instrument is backed by a three-year warranty, ensuring reliable performance in various industrial automation and control applications.
