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.

Interactive Soft Front Panel

PXI SMUs are shipped with an interactive soft front panel for ready-to-run measurements. It includes two modes: one for constantly outputting a DC current or voltage and another for multichannel sweeps. You can monitor and debug the instrument during automated measurement by enabling a debug session.

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.

Custom Transient Response

Digitally control the transient properties of PXI SMUs to maximize stability, reduce overshoot, and greatly decrease test times with NI SourceAdapt, a patented technology on PXI SMUs.

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.

Advanced Sequencing

Change nearly any parameter of PXI SMUs, including aperture time, compliance limit, output mode, and measurement range, without delay to save measurement time during hardware-timed sequences.

Featured Content

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

Learn precision, four-quadrant operation, sweeping, and more features that make SMUs ideal for semiconductor and electronics test.

PXI SMUs combine the power and precision of a traditional box SMU with NI technology that makes them faster, more flexible, and smaller.
