The ultra-high density Model 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 versatil-
ity 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 4×112 and dual 4×56. 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 4×28 or single 4×56
configuration. For larger matrix sizes, analog backplane relays are provided that enable rows to con-
nect to the Series 3700A mainframe backplane. This allows, for example, a matrix of up to 4 rows by
672 columns within a single 3706A mainframe using six Model 3732 cards.
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. Additionally, these relays
provide greater signal voltage (200V) and current (1.2A carry) dynamic range while supporting the
long life and fast actuation times necessary in many automated test applications.
The Model 3732 uses two 78-pin male D-sub connectors for signal and configuration connections.
For screw terminal connections, two accessories are offered. Use the 3732-ST-R for the 16×28 or
dual 8×28 matrix configurations. Use the 3732-ST-C for the 4×112, dual 4×56, or base quad 4×28
matrix configurations.
