HR DAQ software Product number: HRSW-1069

The Data AcQuisition software (HR DAQ) is used to collect and analyse data from a variety of instruments used in physical models such as wave gauges, Acoustic Doppler Velocimeters (ADV) and all pressure sensors.

This comprehensive Windows based data acquisition and analysis program, suitable for 64 analogue input channels, is project based and is split into three sections.

Calibration and scaling of inputs

The calibration section allows the creation of calibration files for use with the acquisition and analysis sections. It provides a comprehensive set of facilities for setting up the calibration files that are used to convert the analogue voltage signals in the model, to data at full scale, assuming Froude or Reynolds scaling.

Data acquisition

HR DAQ is set to collect raw data for a specified period of time at a specified frequency.

Data analysis

After the data has been collected, HR DAQ can be used to perform a number of analysis routines. The principal analysis program includes two routines; one is a Fast Fourier Transform spectral analysis and the other a statistical one.

HR DAQ is used with our wave gauge systems, 8 or 4 channels. We are able to supply different types of A/D devices for use with HR DAQ.
