KNUDSEN Frequently Asked Questions

SounderSuite-USB is KNUDSEN's provided software.

KNUDSEN SounderSuite-USB is the free software package provided with the Sounder and Chirp systems that includes applications for controlling and recording the data from KNUDSEN echosounders, as well as for viewing and printing of data after your survey.

The system requirements for the SounderSuite-USB software package are as follows:

Supported Operating Systems: Computer Hardware (Based on Windows 7)
Windows 10
Windows 8
Windows 7
1GHz (or faster) 32-bit(x86) or 64-bit (x64) processor
1GB RAM (32-bit) or 2GB RAM (64-bit)
70 MB Free Hard Drive Space (for programs only, extra space required for data storage) 1GHz (or faster) 32-bit (x86) or 64-bit(x64) processor


The echosounders come with SounderSuite-USB, a software package of programs for control and recording of data files. These programs communicate with the echosounder through a USB interface. PostSurvey, the program for displaying and printing recorded data, does not need an echosounder to be installed on the system to operate. The EchoControl Client/Server programs provides access to all the normal echosounder control functions (such as gain, power, range and phase etc.) through a graphical user interface familiar to Windows users. EchoControl Client/Server also provide a scrolling, real-time echogram image presentation similar to the printed record on conventional echosounders.

The EchoControl Client/Server, used to control the echosounder, will record data in Binary “echogram” files (.keb) and fully configurable ASCII data files (.kea). SEG-Y and XTF recording is also available on request for most frequencies. The EchoControl program can record all 4 data file types simultaneously allowing the user a wide range of options for interacting with third party survey software.
