For further details about how to adapt the module, please contact the factory directly. A functional block of the V791 module is shown in Fig. 2.1. The 32 input signals are sent to 32 low-noise preamplifiers and relevant shapers. The processed signals are then multiplexed and digitized in order to be transmitted via the serial link.
