EchoSim portable test and calibration instrument.
The EchoSim is a portable test and calibration instrument designed to simplify performance evaluation and troubleshooting of echosounders and transducers including Knudsen equipment. Its main functions are: echo simulation, echosounder transmitter tests, and transducer tests. It currently supports a frequency range from 3.5kHz up to 24kHz and system output powers up to 10kW.
The EchoSim is controlled through a Windows Graphical User Interface (GUI). The EchoSim is a USB device, allowing any computer with host USB port capabilities to serve as a user interface.
