This unit
The Agilent/Keysight E1345A is a 16-channel low-offset relay multiplexer for precision signal routing in VXI systems. This B-size, 1-slot register-based module uses reed relays with thermal offset below 4 µV, enabling accurate measurements across multiple configuration topologies. The E1345A can operate as a single 1×16 three-wire multiplexer, two independent 1×8 three-wire multiplexers for four-wire resistance measurements, or an 1×8 six-wire multiplexer.
Each of two switch banks provides eight channels with common high, low, and guard screw terminals for flexible signal routing.
