Source measure units

A source measure unit or SMU is a source and measurement resource for test applications requiring high accuracy, high resolution, and measurement flexibility. SMUs are sometimes also referred to as source monitor units.

An SMU can precisely force voltage or current and simultaneously measure voltage and/or current. An SMU combines the features of a digital multimeter, true current source, electronic load, power supply, and pulse generator, all into a single, tightly synchronised instrument. Source measure units are considered more useful than a combination of any of the five mentioned instruments due to the instrument’s high accuracy, performance, and versatility.

Our source measure units are extremely cost-effective source/measurement solutions with superior performance. They are categorised into four areas: precision, application-specific, general-purpose, and basic. Available as benchtop or USB models, these instruments have excellent voltage and current sourcing capabilities at the highest precision and multiple software control options allow you to choose the solution that best fits your particular SMU application.

These solutions will improve overall test productivity and lower your cost of ownership.
