Key Features Channel Density and Scalability SMU channel density is increasingly important for multi-site testing and for improving test throughput in applications like reliability that require inherently long stress and measurement cycles. The modularity of the PXI platform allows you to optimize the size of your test system and number of parallel SMU channels by choosing the appropriate chassis and instruments. In a single PXI chassis, you can add up to 17 system SMU channels, mix with higher density SMUs or switches, or combine with other types of instruments to build tightly integrated mixed...

High-Speed Measurement and Update Rate NI system SMUs can sample up to 1.8 MS/s and source up to 100 kS/s, which adds new functionality to a traditionally DC instrument. The high speed sampling rate allows you to use the SMU as a high voltage or current digitizer to capture transient behavior or monitor current consumption over time. The fast update rate allows you to step through large sequences very quickly or use the SMU to generate arbitrary waveforms at low frequencies. Since NI SMUs communicate and share data via a high bandwidth, low latency PCI express interface, you can use the full...

Extended Range Pulsing Certain NI system SMUs are capable of exceeding their 20 W DC power boundary and generating pulses up to 500 W. Generating short, high-power pulses allows you to test devices such as high-brightness LEDs and power transistors while minimizing heat dissipation in the DUT. Having a single device capable of sourcing or sinking up to 500 W reduces the need for stacking multiple SMUs in parallel, and generating short, accurate pulses reduces the need for thermal management systems. Figure 3. The PXIe-4139 can generate pulses up to 10 A with lengths between 50 µs and 1 ms NI-DCPOWER...
