Multi2000 Pocket
Maker：M2M
Co-developed by M2M and EADS Innovation Works (8×32 version), Multi2000 Pocket is a highly portable, lightweight multiplex phased array system which is now available in a 8×32 (pulsers × channels) and a 16×64 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.
