This unit
The Keithley 7071-4 is a Dual 4×12 General Purpose Matrix Card that expands the switching capabilities of Keithley 707A and 708A mainframes. This card enables column expansion up to 720 columns across five 707A mainframes through two independent banks of four signal paths. The matrix configuration supports Dual 4×12, 8×12, or 4×24 arrangements via removable jumpers for segment isolation or reconfiguration. Each crosspoint features 3-pole Form A switching (HI, LO, GUARD) with screw terminals on rows and quick-disconnect 38-pin connectors for column connections.
