The Keithley 3720 offers 2 independent banks of 1x30 two-pole multiplexers for general purpose switching, including temperature measurements. Its analog backplane connection relays provide easy bank and card interconnections. This connection allows the mainframe to reconfigure the card to a single 1x60 two-pole multiplexer or to enable card-to-card expansion for even larger configurations. The 3720 can also be reconfigured to coordinated four-pole operation.
