The Keysight E1351A is a 16-channel FET multiplexer module designed for VXI-based automated test and measurement systems. This B-size, 1-slot register-based module switches 16 independent channels of high, low, and guard signals with break-before-make operation and achieves switching speeds up to 100,000 switches/second from downloaded scan lists. Peak scanning rates reach 13,000 channels/second when integrated with compatible Digital Multimeters. The module opens all FETs on power-up and power-down, ensuring safe signal isolation and eliminating relay wear. Low signal distortion and high isolation characteristics make it suitable for precision analog signal routing in data acquisition and automated test equipment applications.

– Compatibility & Integration
The E1351A shares the same switch card with E1352A, E1353A, E1357A, and E1358A models, with terminal block configuration determining specific function. Compatible DMMs include E1326B and E1411B. The module integrates with E1300B or E1301B B-size VXI mainframes; C-size installation requires E1403C active adapter. Analog bus cable and optional Digital FET MUX-to-DMM cable ship with the module for high-speed measurement synchronization.
