Sercel Specs

The document summarizes the specifications of a seabed seismic data acquisition system including: 1. A server housed in a 2U 19-inch rackable server with Linux OS that handles data computation, storage and client connections. 2. Clients that can be desktops, laptops or remote, running Linux or Windows, and interface with the server software. 3. Field units that can manage up to 8,000 channels in real-time and can be linked to handle more channels. 4. A BCXU-428 unit that connects the field units over Ethernet and provides high-voltage power conversion with safety features. It is housed in a 2U rack and has adjustable high-voltage
