- HR - Measurement Principles This section outlines the shared measurement concepts and processing principles used in Nortek instruments operating in High Resolution (HR) mode, including the Signature 1 MHz, Aquadopp (1 MHz and 2 MHz), and both generations of Vector instruments. While these systems differ in geometry and function, the underlying physics of HR mode remains consistent, primarily leveraging pulse-coherent Doppler processing.

- Initial deployment planning This section guides you through the key considerations for planning a successful deployment, including site conditions, environmental factors, and expected performance. It also helps you select the most suitable Nortek instrument based on your measurement goals and constraints.
- Ocean waves background
- Sensor data check When starting the analysis of a dataset, the sensors can give a first indication of the quality of data retrieved. Their observations can be used to judge the true positioning and orientation of the instrument as well as identify if sudden and unplanned movement occurred. Relying on these sensors requires a successful execution of a Function test prior to the deployment.
- Measurement principles This sections describes the fundamental principles underlying the measurement of velocities using the doppler effect, the assumptions made to utilize this theory and the adjustable user input required. Additionally the available coordinate systems for data collection are described.
- Principles of Operation - Currents This section will provide you an overview of the principles of operation when using a Nortek instrument to measure currents. Most information found here is general and relevant for all different types of current meters and profilers.
