3732

3732 is an ultra-high density reed relay matrix card comprised of four banks, with 4 rows by 28 columns of reed relays. This provides 448 single-pole cross-points for maximum connection versatility in high channel count applications. For even greater flexibility, bank configuration relays are mounted on the card. It offers an automated method of connecting banks to enable two additional matrix configurations - single 4 x 112 and dual 4 x 56. This feature allows the matrix size to be easily adapted to existing or future applications. For differential measurements, a two-pole mode can be selected that enables automatic pairing of cross-points to create a dual 4 x 28 configuration. For larger matrix sizes, analogue backplane relays are provided that enable rows to connect to the series 3700A mainframe backplane. The card uses optimized reed relays that offer both low contact potential and low current offset to minimize the switching errors that often accompany this relay technology.

• Analogue backplane connection relays provide easy card-to-card column expansion
• Ideal for high channel count I-V testing with Series 2600A System SourceMeter® instruments
• Long life dry reed relays (greater than 10⁹ operations)
