The Model 3723 offers two independent banks of high speed 1x30 two-pole multiplexers that are ideal for high speed scanning applications. The two banks can automatically be connected to the Series 3700 mainframe backplane and optional DMM through the analog backplane connection relays. This connection allows the mainframe to reconfigure the Model 3723 as a single 1x60 twopole multiplexer or as a single 1x120 single-pole multiplexer. It also enables card-to-card expansion for even larger configurations.
