What Are PXI Source Measure Units?

PXI Source Measure Units (SMUs) combine high-precision source and measure capability with features designed to reduce test time and increase flexibility.

Unmatched Channel Density

Reduce test time, increase throughput, and meet today's manufacturing requirements by reducing a full rack to a few inches of physical space with up to 408 SMU channels in a single PXI chassis.

Custom Transient Response

Digitally control the transient properties of PXI SMUs to maximize stability, reduce overshoot, and decrease test times with NI SourceAdapt, a patented technology on PXI SMUs that helps you avoid custom circuitry.

Built-In IV Sweep

Reconfigure and repurpose the same SMU across test cases with configuration-based IV sweeps in InstrumentStudio software and a path to more advanced customization in programming environments.

Hardware-Timed Sequences

Get your results faster by removing the communication latency between the host computer and SMU among each measurement of a sequence and, at each step, change various SMU parameters such as output mode, aperture time, current range, and transient response.

High-Power Pulsing

Operate beyond the basic DC power boundary of PXI SMUs by pulsing current or voltage instead of supplying a constant DC source, allowing you to test at high instantaneous power with limited or no heat sink infrastructure.

Featured Content

Reliability engineers are turning toward modular, flexible solutions based on PXI SMUs that can scale to increase reliability data while driving down the cost of test.

With an in-fab ATE based on PXI SMUs, IMEC cut costs by 75% and reduced their project cycle for wafer process flow testing from one month to just three days.

Using PXI SMUs in a multi-site tester, Shining Technologies was able to test 5x more LEDs per second in production compared to a traditional LED tester.
