Chesapeake NI-6210 Description
The Chesapeake NI-6210 is an Analog to Digital Converter (ADC) designed to convert analog signals from sonar systems into digital data that can be processed by hydrographic survey software. This device combines the National Instruments USB-6210 module with the Chesapeake Technology 5-BNC analog interface box, enabling high-resolution data acquisition for various marine applications.
With these specifications, the Chesapeake NI-6210 is a reliable solution for professionals in the fields of hydrography, underwater exploration, and seabed mapping, especially in applications requiring high accuracy in sonar data processing.
Key Features:
- 16-bit Analog to Digital Conversion: Ensures high accuracy in sonar data acquisition.
- Support for Multiple Sensors: Compatible with sidescan sonar, sub-bottom profilers, and other acoustic sensors.
- Flexible Connectivity: Uses a USB interface for communication with a computer, making it easy to integrate with mapping systems.
- Fast Sampling Rate: Up to 250 kS/s, capable of capturing high-speed data for more detailed sonar analysis.
- Integration with Mapping Software: Can be used with SonarWiz software for sonar data visualization and analysis.
