HY1690 Deep Sea Survey Echosounder

 
Overview
HY1690 is a digital deep sea survey echosounder for ocean of 10,000 meters. It is composed of a mainframe and dual-frequency transducer. The mainframe, including an industrial computer system of good capability and two mutual backup transceivers, collects and displays the data. HY1690 operates and controls intelligently by the techniques of Digital Signal Process(DSP) to control backward and steering, TVG and AGC, dispose echo signal, search and follow bottom echo. Lots of techniques used in the machine, such as powerful transmitting circuit, low noise receive circuit, spatial filtering, dynamic threshold detection, TVG compensation and automatic gain control, make the measurement reliable,stable and accurate. The echosounder convinces realtime accurate measurement on different seabed even in condition of rough sea. Data measured by the transceiver is transmitted and saved into the industrial computer. Information of full scale can be saved and searched when checking results in the high-capacity disc.
