Sounder 1620 Echosounder
Overview
A built-in thermal greyscale printer distinguishes this Sounder 1600 model. In addition to the real-time paper record, the printer in the Sounder 1620 can be used with PostSurvey for printing recorded data. SounderSuite-USB software enables the Sounder 1620 user to have real time hard copy printing plus simultaneous scrolling colour echogram display completely under computer control. Both AC and DC power inputs are provided.
The Sounder 1600 Echosounder is KEL's first completely new design since the introduction of the successful 320 Series. Based on the latest generation of 16-bit Digital Signal Processors from industry leader Texas Instruments, the Sounder 1600 becomes the new benchmark for performance and accuracy.
Digital signal processing is key to the performance of the new systems. The Sounder 1600 digitizes the entire incoming signal over an exceptionally wide bandwidth of 230 kHz, and extracts the frequency of interest entirely with digital signal processing software. The digital filters implemented in the Sounder 1600 provide stability and selectivity simply not achievable with analog components, and the TI DSP has the processing power to recover the signal from even the noisiest environments.
Similarly, the transmit signal waveforms are synthesized in software, and are optimized for the bandwidth and frequency response of the transducer. The result is superb frequency agility over a 24 kHz to 210 kHz range with none of the compromises inherent in analog designs.
SounderSuite-USB
All Sounder 1600 systems come with Knudsen SounderSuite software, which provides a flexible and highly functional graphical user interface for the sounder on any Windows PC. In addition to the user interface, SounderSuite provides a high-resolution echogram display, sensor interface (heave, GPS, etc.) and datalogging functions.
The first three members of this new echosounder family are the Sounder 1600, 1610, and 1620. Common to all of the new systems is full-speed (12 Mbps) USB 2.0 connectivity. Multiple Sounder 1600 units can be connected to the same PC to provide a total of up to four simultaneous channels, which may be any combination of sidescan and vertical.
