Introduction to the Model 3723 card
The Model 3723 has two independent banks of high-speed 1×30 two-pole multiplexers that are ideal
for high-speed scanning applications (see next figure). The two banks can automatically be
connected to the Series 3700A mainframe backplane and an optional digital multimeter (DMM)
through the analog backplane connection relays. This connection allows the mainframe to reconfigure
the Model 3723 as a single 1×60 two-pole multiplexer or as a single 1×30 single-pole multiplexer. It
also enables card-to-card expansion for even larger configurations.
By using high-speed reed relays with actuation times of less than 0.5 ms, this card can meet the
requirements of demanding throughput applications. Another feature of the Model 3723 is its single-
ended, one-pole mode, which supports up to 120 channels of single-wire measurements. The Model
3723 uses two 78-pin D-sub connectors for signal connections. For screw terminal connections, use
the Model 3723-ST for two and four-pole configurations or the Model 3723-ST-1 for single-wire
applications.
