In this project Hard- and Software has been developed for Ultra Sound Phased Array pipeline weld inspection. The project involved high voltage transducer excitation, sensitive analogue signal detection, 100MHz A/D conversion of hundreds of parallel channels resulting in a 600Gbit/s data rate and digital signal processing. Key design challenges were the combination of sensitive analogue electronics with high voltage circuits and high bandwidth digital circuits in a small package. The designed PCB consist of 20 layers and contains approximately 6500 components. High speed signal analysis was done using Mentor Graphics tools to verify signal integrity during the design phase.
