New Matrix Card Expands Keithley's Series 3700

Keithley Instruments, Inc., a world leader in advanced electrical test instruments and systems, today announced an expansion of its Series 3700 System Switch/Multimeter and plug-in card family with the addition of a new plug-in switching card, the Model 3731 6´16 High Speed, Reed Relay, Matrix Card. Its exceptional voltage and current characteristics (200V, 1A switched or 2A carry signal capacity) make it ideal for use in multi-channel I-V testing in conjunction with Keithley's Series 2600A System SourceMeter® instruments.

The Model 3731 is a two-pole, 6 row ´ 16 column reed relay matrix card. 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 Model 3731's 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.

Keithley's Model 3731 6´16 High Speed, Reed Relay Matrix Card is priced at $1995 USD. Availability is four to five weeks after receipt of order.
