ROMIS PAUT is the phased array based variant of the ROMIS electronics family. As today’s phased array applications are intended to provide high inspection density combined with high inspection speed, ROMIS PAUT is based on a rigorously implemented parallel approach combined with a paint-brush evaluation unit. The three variants of ROMIS PAUT offer different numbers of channels: the high-end unit is a 256:256 parallel system, the medium and small units offer a 128:128 parallel and a 2x 32:128 channel configuration. The option to drive an external multiplexer allows the future use of matrix arrays with an aperture up to 256 elements. Last but not least, the lean, power-saving design allows closed housings with passive cooling also for the 256 parallel channel version.
