The National Instruments 782435-01, known as the PXIe-4145 High-Precision PXI Source Measure Unit (SMU), is engineered for precision testing in high-pin-count applications. This device features four channels, each capable of providing a DC voltage range of ±6 V, allowing for versatile test configurations across various measurement setups. With its exceptional sample rate, the 782435-01 efficiently characterizes devices under test, significantly reducing measurement times. Utilizing SourceAdapt technology, this SMU maximizes stability in response to load variations, while its advanced high-speed sequencing engine enables synchronization with other instruments, including digital test modules and switches.

This instrument excels in four-quadrant operation, enhancing testing and characterization capabilities. Each channel incorporates 4-wire remote sensing, supporting a source and sink current range from 10 μA to 500 mA. The 782435-01 is equipped with multiple trigger types, including Start, Source, Sequence Advance, and Measure, all of which feature configurable polarity to accommodate specific testing needs. For convenient connectivity, the device includes male D-Sub (25-position) connectors on the front panel.

In terms of power requirements, the device operates at 2.1 A on a 12 V rail and 2.9 A on a 3.3 V rail. It functions optimally within a temperature range of 0 °C to 55 °C. The physical dimensions of the 782435-01 are 2.0 cm × 13.0 cm × 21.6 cm (0.8 in. × 5.1 in. × 8.5 in.), with a weight of 408 g (14.39 oz), making it suitable for a variety of laboratory and industrial settings. The product is backed by a three-year warranty and is manufactured by National Instruments, ensuring reliability and quality in performance.
