Source Measure Units

A Source Measure Unit (SMU) is an advanced instrument that combines the capabilities of a precision power supply, a digital multimeter, and an electronic load in a single device. SMUs are designed for applications where accurate voltage and current sourcing, as well as simultaneous measurement, are critical.

Unlike traditional power supplies, which simply provide voltage or current, SMUs offer precise control and rapid feedback, allowing engineers to characterize and test components with exceptional accuracy. This makes them essential in industries such as semiconductor testing, battery research, materials science, and electronic component validation.

Key Features of an SMU:

• Four-Quadrant Operation – Can source and sink power, enabling full testing of active and passive components.
• High Accuracy & Resolution – Delivers precise voltage and current control down to microamp or even picoamp levels.
• Fast Response Time – Ideal for transient and dynamic testing applications.
• Integrated Measurement Functions – Reduces the need for external meters, simplifying test setups.

Whether you’re developing next-generation semiconductors, testing high-efficiency LEDs, or analyzing battery performance, SMUs provide a versatile and reliable solution for precision measurement and power control.
