HY1690 is a type of echosounders which is applied in the offshore survey. Its mainframe, consisting of an Industrial Control Computer System and two transceivers which work standby for each other, is responsible for the data acquisition and processing.

HY1690 realizes the intelligentized operation and control of echosounders by adopting digital signal processing technology and display technology of computer graphics. All operations of echosounders can be done without the adjusting knob. The core technology of the echosounder is high-speed digital signal processor(DSP), which contributes to emission and reception control, TVG and AGC control, digitization and processing of echo signals, searching and tracking of bottom echos, etc. Furthermore, its particular high-powered emitting circuit, receiving circuit and spatial filtering with low noise, dynamic detecting threshold, TVG compensation device, automatic gain control, greatly improve the reliability, stability and accuracy of bathymetry. In spite of bad sea conditions, all of these ensure accurate measurement of different types of seabedsthe in the real time .

The bathymetric data collected by the transceiver are transmitted to and conserved in the industrial control computer by USB. The high-capacity disk can not only store all the acoustic and graphic information in the full measuring range, but also provide a platform for information retrieval.
