The Keithley 2612B is a dual-channel System SourceMeter source measure unit with isolated channels for I-V characterization and automated component testing. Each channel combines voltage or current sourcing with electrical measurement and four-quadrant source or sink operation.

The published DC envelope includes 200 V at 100 mA and 20 V at 1.5 A per channel, with a maximum DC power specification of 30.3 W per channel. A separate pulse region permits 10 A at 5 V for up to 1 ms at a maximum 2.2% duty cycle. These voltage and current limits are operating points rather than simultaneous maxima. Full-power sourcing is specified through 30 °C ambient; higher ambient temperatures and sink operation require additional derating.

Embedded Test Script Processor control runs stored test sequences, and TSP-Link supports coordination with compatible instruments. Contact Check, digital I/O, GPIB, rear USB device control, RS-232, and Ethernet support system integration. The front USB host connection serves mass-storage devices. Local or four-wire remote sensing can be selected to suit the test setup.

The specification rows below use the 2611B/2612B/2614B section of the official 2600B data sheet, with the 2612B-specific channel and feature distinctions retained. The 100 fA default current display resolution applies to the 100 nA range in single-channel display mode; that range is unavailable in High Capacitance Mode. Resolution does not state measurement accuracy.

Manufacturer image reference: The official group photograph shows 2611B, 2612B, and 2614B instruments together. This listing is for the Keithley 2612B; the photograph does not represent a multi-instrument package or establish the offered unit’s accessories.
