Model 3723 dual 1×30 high-speed multiplexer card
The Model 3723 has two independent banks of high-speed 1×30 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 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 0.5ms, 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 37230-
ST-1 for single-wire applications.
