Keysight Modular Source Measure Units

视频

This video introduces Keysight Modular Source Measure Units (SMUs), designed to deliver high‑precision, high‑density sourcing and measurement capabilities in compact modular platforms. Available as standalone systems or PXIe modules, these SMUs allow engineers to balance precision and throughput, enabling configurations that match specific application requirements across semiconductor testing, materials characterization, automated test equipment (ATE), and high‑volume production environments.

The standalone modular SMU mainframe supports up to 20 fully synchronized SMU channels in a 1U form factor, offering exceptional channel density with synchronization accuracy better than 100 ns per channel. This makes it ideal for multi‑device parallel testing, array‑level measurements, and timing‑sensitive characterization. Modules include precision, pulsed, and digitizing SMU options that deliver up to 3.5 A DC or 10.5 A pulsed current, along with high measurement resolution suitable for advanced R&D and automated validation.

PXIe modular SMUs integrate seamlessly into larger PXIe systems, providing up to five channels per module with a wide range of voltage, current, and measurement capabilities. These modules enable scalable architectures that support real‑time synchronization, high‑speed sampling, multi‑channel biasing, and flexible triggering for complex mixed‑signal and semiconductor applications. Engineers can combine multiple modules to create high‑density, tightly synchronized SMU arrays that support device‑under‑test (DUT) parallelization or multi‑bias experiments.

Modular SMUs support voltage ranges from 20 V to 210 V, sampling rates up to 15 MSa/s, current capabilities up to 3.5 A DC and 10.5 A pulsed, and measurement resolutions as fine as 6 μV and 100 fA. These capabilities make them well‑suited for characterizing advanced semiconductor devices, power components, sensor arrays, materials, and next‑generation electronics across both R&D and automated test environments.
 

Key features include:

  • High Channel Density: Configure up to 20 SMU channels in a 1U standalone mainframe with <100 ns synchronization.
  • Precision Sourcing & Measuring: Access pulsed and digitizing module options delivering up to 3.5 A DC or 10.5 A pulsed current.
  • PXIe SMU Modules: Scale up to 5 channels per module with flexible voltage, current, and measurement ranges.
  • Wide Measurement Ranges: 8 V to 210 V outputs, 6 μV / 100 fA resolution, suitable for advanced production testing.
  • High‑Speed Sampling: Sample rates up to 15 MSa/s for high‑speed device characterization and transient capture.
     

Modular SMUs combine benchtop‑grade precision with high‑density modular scalability, enabling fast sampling, synchronized multi‑channel testing, and flexible configurations for semiconductor, materials, and automated test applications across both R&D and production environments.
