20W to 100W Bench-Top Source Measurement Unit (SMU) Instruments
Keithley's industry-leading SourceMeter instruments
Keithley SourceMeter instruments combine source, measure, and control capabilities with ease of use in one compact unit—eliminating many of the complex synchronization and connection issues associated with using multiple instruments. Each of these source measure unit (SMU) instruments can act as a voltage source, a current source, a voltage meter, a current meter, and an ohmmeter.
