SyQwest manufactures all components of the TD-1479 LSA and OB-122 WAA outboard electronics units. These are the primary outboard electronics for both of these US navy submarine sonar systems. Each LSA and WAA OBE contains electronics to provide amplification, filtering, analog-to-digital conversion, and signal encoding. Digital acoustic data for all the hydrophone channels processed within the OBE are transmitted via serial data lines to the inboard Sonar system processing electronics.
