This unit
The Keithley 7012C is a 4×10 matrix switching card engineered for signal routing within Keithley 7001 and 7002 switch mainframes. Built around a 2-pole Form A (Hi, Lo) contact configuration, this card delivers precision switching for sensitive measurement environments while minimizing signal degradation and crosstalk. The card connects via a 96-pin male Euro card connector and supports DC signals up to 110V at 1A (30VA resistive load) and AC signals up to 125V RMS or 175V peak at 1A (60VA resistive load). With contact potential below 1 µV per pair and channel resistance under 1 Ω per conductor, the 7012C maintains signal integrity across demanding applications. Isolation exceeds 10⁹ Ω across all paths, while crosstalk performance reaches -40 dB at 1 MHz with a 50 Ω load.
