Model 3722 dual 1x48 high-density multiplexer card
The Model 3722 has two independent banks of 1x48 two-pole multiplexers,
which is ideal for applications that require a high channel count. 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 card as a single 1×96 two-pole
multiplexer, or to enable card-to-card expansion for even larger configurations.
Another feature of this card is the latching electromechanical relays that can
accommodate 300 V, 1 A switched signal levels.
The Model 3722 uses two 104-pin D-sub connectors for signal connections. A
solder-style connector kit (Model 3792-KIT104-R) and pre-assembled cables
(Models 3722-MTC-1.5 and 3722-MTC-3) are available for card connections.
