Additional Features:

• Four independent banks of 4x28 single pole matrices
• 200V, 1.2A carry or 0.75A switched signal capacity; 15W, 15VA
• Bank configuration relays enable alternative matrix sizes, including dual 4x56 (1 wire), single 4x112 (1 wire), and single 4x56 (2 wire)
• Optional accessory, Model 3732-ST-R, enables screw terminal access and additional matrix sizes, including dual 8x28 (1 wire), single 16x28 (1 wire), and single 8x28 (2 wire)
• Analog backplane connection relays provide easy card-to-card column expansion
• Long life dry reed relays (>10⁹ operations)
• Ideal for high channel count I-V testing with Series 2600A System SourceMeter® Instruments

The ultra-high density Keithley 3732 matrix card is comprised of four banks, each with 4 rows by 28 columns of reed relays. This provides 448 single-pole crosspoints for maximum connection versatility in high channel count applications. For even greater flexibility, bank configuration relays are mounted on the card. They offer an automated method of connecting banks to enable two additional matrix configurations: single 4x112 and dual 4x56. This feature allows the matrix size to be easily adapted to existing or future applications. For differential (2-wire) measurements, a two-pole mode can be selected that enables automatic pairing of crosspoints to create a dual 4x28 or single 4x56 configuration. For larger matrix sizes, analog backplane relays are provided that enable rows to connect to the Series 3700 mainframe backplane. This allows, for example, a matrix of up to 4 rows by 672 columns within a single 3706 mainframe using six Model 3732 cards.
