Source Measure Units Catalog

The Keysight Source Measure Units Catalog provides a comprehensive overview of benchtop and modular source measure units (SMUs) engineered to deliver precise voltage and current sourcing with simultaneous measurement capabilities. Organized into Essential, Expert, and Pro performance grades, the catalog covers three capability classes that support up to 6.5 digits source resolution and span from 10 fA to 1 pA minimum current measurement resolution. The catalog includes benchtop SMUs for a wide range of applications, including everyday device characterization, power electronics testing, and high-speed transient analysis.
 

Explore the three source measure unit performance grades:

• Essential SMUs come in one class, the SM1-class, and include the B2910CL and B2901CL. They are designed to deliver reliable, high-performance electronic testing in a compact and affordable benchtop unit. Our Essential SMUs combine 6-instruments-in-1 and 5.5-digit source resolution, making them ideal for a wide range of applications, including device characterization, circuit testing, and educational use. Additional features include support for 4-quadrant operation, an intuitive graphical user interface, and flexible connectivity options such as USB, LAN, and GPIB. Additionally, use built-in math and limits to perform basic calculations on measured data to extract parameters like resistance and power without exporting raw data and sets pass / fail limits for automated testing.
  
  
• Expert SMUs come in one class, the SM2-class, and include the B2902C and B2901C. They are available in both single- and dual-channel configurations, providing greater flexibility for parallel IV measurements and power electronics testing. With pulsed measurement capabilities, Keysight Expert SMUs offer 7-in-1 functionality, ideal for capturing detailed IV curves using short pulses that minimize power and heat, protecting sensitive devices in semiconductor and higher-level materials testing. Expert SMUs also deliver up to 3 A output current, ideal for testing high-current devices, and supports high-volume data collection for long-duration automated testing with 100,000 points of memory per channel and an infinite number of trigger counts. Dual-view mode displays both numerical data and graphical plots on the front-panel display, enabling instant correlation of measured values and device behavior.
  
  
• Pro SMUs come in one class, the SM3-class, and include the B2912C and B2911C. Pro SMUs are our most sophisticated and highest-performance models, ideal for ultra-high-precision measurements and high-speed transient analysis. Our Pro SMUs feature a high 6.5-digit source resolution, ultra-fast sampling with 100 kSa/s at 10 μs intervals, and the highest measurement accuracy in our benchtop SMUs, making them ideal for simulating real-world conditions for testing power-intensive devices in higher-level R&D, power electronics, and nanomaterial research. Capabilities like roll-view mode provide a real-time, scrolling graph of SMU measurements, ideal for continuous monitoring, slow changes, or diagnosing device behavior as it happens. Additionally, high-capacitance drive mode enables stable voltage or current sourcing into high-capacitance loads – like capacitors, long cables, or power devices – without oscillation or delays.
   

Additionally, Keysight offers modular source measure units that are designed for scalability and flexibility. Their compact, modular form factor enables efficient multichannel configurations that are ideal for both R&D and high-volume production testing. Mix and match modules with varying performance and capabilities to tailor the modular SMU to your needs.
 

This catalog also highlights software and accessories that extend the capability of Keysight SMUs. A wide variety of software solutions are offered for control, analysis, and measurement. The software provides an intuitive and powerful interface for controlling and automating SMU operations, enabling you to quickly set up tests, visualize results, and analyze data with precision. Track and record your source meter output to understand the impact of the power draw for specific events. Pair your SMU with the adapters, cables, and a rack-mount kit to make the right measurements for your application.
