Keithley Intros Hi Speed Matrix Switching Card
Matrix switching card.
Cleveland, OH — Keithley Instruments, Inc. has expanded its Series 3700 System Switch/Multimeter and plug-in card family with the addition of a new plug-in switching card. The Model 3731 is a high-speed, reed relay matrix card with exceptional voltage and current characteristics (200V, 1A switched or 2A carry signal capacity).

The card is suitable for use in multi-channel I-V testing in conjunction with the company's Series 2600A System SourceMeter® instruments. The card is a two-pole, 6 row x 16 column reed relay matrix. High-speed dry reed relays (<0.5ms actuation times) make it an excellent choice for applications that demand a combination of high throughput and long switch life. The relay contacts are rated for more than one billion no-load switch operations.

As a matrix card, the Model 3731 offers users the flexibility to connect any of up to six differential instrument channels to any combination of 16 devices under test (DUTs). Any row can be connected to the Series 3700 mainframe's analog backplane by using the analog backplane connection relays. This allows for easy matrix column expansion. A single Model 3706 mainframe can support a matrix of up to 6 rows by 96 columns when six Model 3731 cards are installed. By using the TSP-Link® master/slave communication bus, multiple mainframes can be linked to create even larger switch configurations. The analog backplane also offers automated access to the high performance multimeter built in to the Model 3706 mainframe, one of the most popular Series 3700 options.

The Model 3731 uses two 50-pin male D-sub connectors for signal connections. A detachable Model 3731-ST accessory is available for making screw terminal connections.
