Keysight Pro Source Measure Units

This video introduces Keysight Pro Source Measure Units (SMUs), designed to deliver the highest level of precision, measurement resolution, and dynamic sourcing capability available in a benchtop SMU. These instruments support ultra‑high‑precision characterization, high‑speed transient measurements, and advanced sourcing modes essential for the most demanding R&D applications, including semiconductor device analysis, quantum research, nanomaterials, precision sensors, and power electronics validation. Pro SMUs offer six‑and‑a‑half‑digit measurement resolution, enabling engineers to capture extremely low‑level signals with exceptional accuracy and repeatability.

With a fast 100 kSa/s sampling rate, Pro SMUs can accurately capture transient responses in fast‑switching devices, providing the measurement fidelity required for characterizing device behavior under rapid changes in voltage or current. A built‑in roll‑view mode displays a continuous, real‑time scrolling graph of SMU measurements—ideal for live monitoring, visual troubleshooting, and long‑duration trend analysis. These capabilities significantly enhance the workflow for debugging, reliability studies, and dynamic device behavior evaluation.

A high‑capacitance drive mode ensures stable voltage and current sourcing into high‑capacitance loads, preventing oscillation and minimizing settling delays. This mode is particularly valuable when testing devices such as capacitors, long‑cable systems, high‑power components, and heavily filtered circuits. Combined with 4‑quadrant sourcing and sinking, Pro SMUs offer full flexibility for complex device characterization across a wide range of bias conditions.

Pro Source Measure Units feature up to 210 V and 3 A of continuous output—or up to 10.5 A pulsed—enabling evaluation of advanced semiconductor devices, power systems, and high‑current components. With 10 fA current‑measurement resolution and a 100 kSa/s sample rate, these instruments set the benchmark for accuracy, speed, and sourcing capability in high‑performance benchtop SMUs. Their integrated functionality and precision make them ideal for next‑generation R&D labs and applications requiring the highest confidence in measurement results.

Key features include:

• 6.5‑Digit Precision: Achieve highly accurate measurements for low‑level signals with exceptional repeatability.
• Ultra‑Fast Sampling: Capture fast transient responses with a 100 kSa/s sampling rate.
• Roll‑View Mode: Real‑time scrolling measurement display for continuous trend observation.
• High‑Capacitance Drive Mode: Ensures stable sourcing into high‑capacitance loads such as capacitors, long cables, and power devices.
• High Output Capability: Up to 210 V and 3 A continuous, or 10.5 A pulsed, for high‑power and advanced device testing.
   

Pro Source Measure Units offer the highest accuracy, fastest sampling, and most advanced sourcing modes in Keysight’s SMU portfolio—ideal for precision R&D, semiconductor device engineering, nanomaterial analysis, and next‑generation electronic testing requiring uncompromising measurement performance.
