The Agilent/Keysight E1343A is a 1-slot B-size VXI relay multiplexer module delivering high-voltage switching across 16 channels with configurable architectures. Built on reed relay technology, the module supports operation as a single 1×16 three-wire multiplexer, two independent 1×8 three-wire multiplexers, or a 1×8 six-wire multiplexer—enabling flexible test configurations from simple analog routing to four-wire resistance measurements and precision 6-wire setups. Register-based control via SCPI commands and downloadable firmware provide straightforward integration into automated test systems.

– Compatibility & Integration
The E1343A fits directly into B-size VXI mainframes (Agilent E1300B, E1301B). For C-size mainframe integration, deploy the E1403C active adapter. Analog bus cables enable connection with companion instruments such as the E1326B DMM. Instrument drivers and software support include I-SCPI (Win 3.1, Series 700), C-SCPI (LynxOS, Series 700), VXIplug&play frameworks, and panel drivers.
