Enables data transfer and control signaling through conditioned, level-shifted, differential I/O, with clock distribution, data buffering, and timing alignment. Supports connectorized external interfaces, impedance-controlled traces, and protection features to maintain signal integrity at the instrument’s data-rate range. Used to integrate measurement systems with peripheral hosts or analyzers by translating and routing data and control paths without performing primary measurement. ## Images - - - -
