The Keithley 2612B is a dual-channel System SourceMeter (SMU) that combines precision voltage and current sourcing with measurement capability in a single instrument. It delivers four-quadrant operation, functioning as both source and sink across voltage and current domains. The 2612B integrates power supply, current source, digital multimeter, arbitrary waveform generator, pulse generator, and electronic load functionality. Built on the 2600B Series platform, it employs Test Script Processor (TSP) technology for high-speed test automation and TSP-Link for multi-channel parallel testing.
