Multi-function: It integrates the functions of traditional analog hydrophone, amplification and conditioning circuit, acquisition, storage, and Ethernet transparent exchange.
Fast cascading array: With two 100/1000Mbps self-adaptive Ethernet interfaces (uplink network port and downlink network port), it is convenient to quickly form a large-scale synchronous underwater acoustic measurement or observation processing system through cascading arrays.
High synchronization accuracy: PTP (IEEE1588) protocol is used to realize the synchronous collection of data and synchronous message transmission between hydrophones via Ethernet, automatic and fast synchronization after power-on, and the synchronization accuracy reaches hundreds of nanoseconds.
Low self-noise, large dynamic range, strong versatility.
Customized working frequency band, fixed gain and adjustable gain range.
The HY-AS007 digital hydrophone is a multifunctional underwater acoustic signal acquisition unit. The digital hydrophone is convenient to quickly form a large-scale synchronous underwater acoustic measurement or observation processing system through cascading arrays, and has high-precision synchronous transmission capability of hundreds of nanoseconds. Only one cable is used between the hydrophones to realize the functions of communication, synchronization and power supply, and the multiplexing link technology greatly reduces the number of cables on the basis of the traditional solution.
