The Keysight E1346A Single-Ended Relay Multiplexer is a B-size, 1-slot, register-based VXI module that switches 48 channels of high connections and one channel each of low and guard. This module consists of a component and a terminal block that plugs onto the component card. An analog bus connector on the faceplate provides easy connection to an E1326B DMM, E1411B DMM, and/or other slot-adjacent multiplexers.
Common high, low, and guard signals are connected by tree switch to both the tree-switch terminals on the terminal card and the analog bus connector. Removal of a factory-installed jumper on the component card isolates the low from the guard input. One analog bus cable is shipped with each module, making it easy to connect multiplexer common outputs together for slot-adjacent modules.
