The Keithley 2420 is a 60W SourceMeter integrating voltage source, current source, voltage meter, current meter, and ohmmeter into a single instrument. It delivers ±5µV to ±60V sourcing, ±1µV to ±60V measurement, and ±100pA to ±3A current range with 0.012% basic accuracy and 6½-digit resolution. Built for 4-quadrant operation, it sources and sinks across semiconductor, automotive, and medical device characterization and production test environments.
