ModulUS3 offers a platform of pre-engineered coax, cable, and termination options. The basis for the platform is two true coax configurations that completely shield signal lines to provide consistency and signal protection compared to other non-coaxial constructions. The entire interconnect system maintains crosstalk at less than -30 dB at 10 MHz on finished assembly to fall below acoustic crosstalk found in many transducers.
