The Model 7071 is a general purpose, three-pole 8 x 12 (8 row by 12 column) matrix card. Some of the key features include: • Guard capability. Each HI/LO path pair on the PC board is surrounded by a third path that can be used for guarding. • Low contact potential and offset current for minimal effects on low-level signals. • Quick disconnects using the "rack and panel" receptacles on the rear panel or terminal blocks on the PC board.
