Features

320C Digital Echosounder

Features of the 320C Digital Echosounder include:

  • Embedded PC.
  • Windows Control.
  • Internal Logging of Digital Echogram.
  • Simple Touch Screen Control.
  • Network Ready.
  • Precision Bottom Tracking.

Connectability.
Four RS232 serial ports support communication with personal computers (and laptops), GPS receivers, NMEA input and output devices, sound velocity sensors, heave sensors, remote depth displays and survey data loggers.

Digital Signal Processing (DSP).
The 320 echosounders do all signal processing digitally. There are many advantages to an all-digital system, including the inherently higher performance and greater stability of digital filters. The processing is performed in software which can be programmed to accommodate any frequency, bandwidth, or pulse length, eliminating the need for multiple analogue hardware filters.

Correlation Processing (optional).
The 320C has the option to employ linear FM sweep (chirp) transmit pulses and correlation processing of the received signal to achieve up to 20dB signal to noise (SNR) gain over conventional CW echosounders, for improved depth capability and bottom detection reliability.

Easy Transducer Interface.
The Knudsen 320 Series Echosounders can be easily interfaced to most existing transducers, saving the expense of new transducers and dry dock installation.
