Sounder 1600 Series Echosounders

Overview

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.

The first four members of this new echosounder family are the Sounder 1600, 1610, 1620 and 1650. 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.

Sounder 1600 With up to four channels in a single 3U rackmount case, the Sounder 1600 provides an economical solution for survey vessels where splashproof packaging is not a requirement. The standard unit is fitted with a universal input power supply (85-365VAC), but 9-36 volt DC power is an option.
Sounder 1610 A waterproof plastic case makes this model ideal for portable applications and small boats. It is available in single or dual-channel versions, with 9-36 VDC power.
Sounder 1620 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 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.
Sounder 1650 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 XPe colour LCD computer running KEL's SounderSuite software. All of this is packaged in an elegant fully-machined aluminum housing reminiscent of the classic 320M.
