This unit
The Keithley 3723 is a dual-bank, high-speed multiplexer card for the Series 3700A mainframe, delivering configurable switching across 30 to 120 channels. Two independent 1×30 two-pole multiplexer banks interconnect via mainframe relays to form 1×60 two-pole, 1×30 four-pole, or 1×120 single-pole configurations. High-speed reed relays with actuation times below 0.5 ms enable scanning rates exceeding 800 channels/s, making the 3723 ideal for multi-channel I-V characterization, parametric testing, and complex data acquisition. The card maintains contact potential of ±6 μV (differential) and ±12 μV (single-ended) while supporting 1-, 2-, and 4-wire measurement topologies. Rated for switching up to 200 V DC/RMS at 1 A with 1.25 A carry capacity, it delivers 20 MHz bandwidth and 10^10 Ω isolation across all configurations.
