The Keithley 7015-C is a 40-channel solid-state multiplexer card engineered for high-speed multipoint measurement and signal routing in automated test systems. Built on four independent 1×10 2-pole multiplex banks (or two independent 1×10 4-pole banks), it delivers scanning speeds exceeding 300 channels per second when paired with Keithley 7001 or 7002 mainframes. Solid-state switch technology provides sub-500 µs actuation times, contact potentials below 5 µV per channel pair, and MTBF exceeding 30,000 hours for extended operational reliability.
