Sounder 1650 Echosounder
Overview
The most comprehensively equipped member of the new Sounder 1600 family, the Sounder 1650 combines the advanced dual-frequency DSP echosounder functionality and built-in 32 greyscale printer of the Sounder 1620 with an embedded Windows XP colour LCD computer running KEL's SounderSuite-USB software. All of this is packaged in an elegant fully-machined aluminum housing reminiscent of the classic 320M.
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-USB 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-USB provides a high-resolution echogram display, sensor interface (heave, GPS, etc.) and datalogging functions.
