National Instruments 783762-01 PXI Source Measure Unit 

National Instruments part number 783762-01 is an identifying part number for the PXIe-4135, a Precision System PXI Source Measure Unit. The instrument is a precise system source measure unit (SMU) that supports the 4-quadrant operation. 

It can supply up to 40 W of DC power and pulse up to 500 W. It comes with advanced analog-to-digital converter technology and native triaxial connectors that enable high-precision measurements with a current resolution of 10 fA or high-speed acquisitions up to 1.8 MS/s. This module incorporates SourceAdapt technology to optimize stability and measurement accuracy by adjusting the transient response to match load characteristics. Suitable for various applications including manufacturing tests, board-level tests, and lab characterization, it can handle devices like ICs, power management ICs (PMICs), RFICs, LEDs, and optical transceivers. 

The interactive soft front panels can be used for basic measurements and debugging automated applications. The driver features help files, documentation, and ready-to-run example projects to assist in test code development. It also includes a programming interface compatible with a variety of development environments. Engineers can use the modular National Instruments 783762-01 SMU to build parallel, high-channel-count systems with up to 68 SMU channels in a single PXIe chassis, scalable to several hundred channels. Users can increase test throughput by leveraging a high-speed communication bus, deterministic hardware sequencing, and digital control loop technology to custom-tune the SMU response for any device under test. 

Additionally, they can control the SMU response through software, eliminating long wait times for SMU settling and providing the flexibility to minimize overshoot and oscillations. The PXIe-4135 can be identified by two part numbers. Part number 783762-01 is characterized by a maximum DC sink power of 12 W, a maximum DC source power of 20 W, and a pulsed current range of -3 A to 3 A.
