Chirp 3200 Echosounder
Overview
With one or two 2-KWchannels in a single 3U rackmount case, the Chirp 3200 provides a high performance solution for survey vessels where splashproof packaging is not a requirement.
The Chirp 3200 family of scientific echosounders sets a new standard in high performance deep water sub-bottom profilers. Based on the latest generation of 32-bit floating point digital signal processors from industry leader Texas Instruments, the Chirp 3200 systems provide leading edge solutions for today and into the future.
The basic Chirp 3200 system can accommodate one or two low frequency channels and a single high frequency channel. The low frequency channels feature 24-bit digitization with exceptional instantaneous dynamic range of 118 dB and overall dynamic range exceeding 160 dB. A 16-bit digitizer is provided for an optional high frequency channel.
As in all Knudsen echosounder systems, digital signal processing software plays a key role. All channels are designed for frequency agility as well as fullspectrum chirp and correlation processing to take maximum advantage of the bandwidth offered by modern transducers.
SounderSuite-USB Software
All Chirp 3200 systems come with Knudsen SounderSuite-USB software, which provides a flexible and highly functional graphical user interface for the sounder on anyWindows PC. In addition to the user interface, SounderSuite-USB 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 Chirp 3200, 3210 and 3260. Common to all of the new systems is hi-speed (480 Mbps) USB 2.0 connectivity. Multiple Chirp 3200 or Sounder 1600 units can be connected to the same PC to provide a total of up to four simultaneous channels.
