Introduction to the Model 3731 card
The Model 3731 is a two-pole, six-row by 16-column reed relay matrix card. Using high-speed reed
relays with actuation times of 0.5 ms, this card meets the requirements of demanding throughput
applications. In addition, the Model 3731 is designed for long life, exceeding one billion operations.
The Model 3731 can connect up to six differential instrument channels to any combination of 16
devices under test (DUTs). Any row can be connected to the Series 3700A mainframe backplane
using the analog backplane connection relays, allowing for matrix column expansion. A matrix of up
to six rows by 96 columns can be supported within a single Model 3706A mainframe (using six Model
3731 cards).
