Multi2000 Pocket Multiplex Systems

Co-developed by M2M and EADS Innovation Works (8x32 version), Multi2000 Pocket is a highly portable, lightweight multiplex phased array system which is now available in a 8x32 (pulsers × channels) and a 16x64 configuration. The Multi2000 software is based on the CIVA software package for ultrasound propagation simulation developed by the French atomic energy research institute CEA. It performs calculation of the delay laws, controls the data acquisition, and displays in real-time the measurement results.Multi2000-Pocket 16x64
