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.
Keysight Technologies is the leader in the Source/Measure and Source/Monitor Unit (SMU) market. Keysight provides a wide range of SMU products, which are categorized into four areas: Precision, Application Specific, General-Purpose, and Basic.
