The Keysight/Agilent/HP E1345A Screw Terminal Block is a terminal interface component for the E1345A General-Purpose Reed Relay Multiplexer, a B-size, 1-slot VXI module. It provides screw terminals for direct connection of discrete wires to measurement systems, enabling flexible signal routing and access across 16 switching channels. The terminal block attaches to the E1345-66201 component card and supports multiple multiplexer configurations: a single 1 × 16 three-wire multiplexer, two independent 1 × 8 three-wire multiplexers for four-wire measurements, or a 1 × 8 six-wire multiplexer. Reed relay switching delivers low thermal offset performance with less than 4 µV thermal offset per channel.
