Additional Features:

  • Low cost

The Keithley 7075 is a general purpose multiplex switching card that consists of eight banks of independent 112 multiplexer switching. Each bank has two switched circuits (HI and GUARD). The row is connected through jumpers on the card to the general purpose analog backplane in the Model 707A or 708A switching mainframe. This provides the interconnect between cards for multiplexer expansion (124, 136, etc.). Jumpers may be removed to isolate any bank. A single card can be expanded to 196 by reconfiguring the supplied bank-to-bank jumpers. Eight 25-pin D connectors are provided for bank connections and one for row connection.
