To allow evaluation of the software example data is available for download. This contains a number of unconverted Polysync (*.vno) files and an example VSA dataset.
Extract the data from the zip file. Either open the VSA, create a new multiple probe dataset and import the *.vno files, or open the VSA, click the "Open existing dataset" button and open the example dataset file ("Example.majds").
The data was collected in an experimental flume. One probe was used to traverse a cross-section of the flume, the other was at a fixed position upstream, and used to monitor flow stability (i.e. the streamwise velocity measured by the fixed probe should be approximately constant).
