The VDI monitor consists of a standard PC type, 1 to 2 monitors, a stand and an acquisition unit BioSDA09. The computer is used to control measurement, data processing and storage.
The VDI-vision software was developed for measurement, control, online processing, and display of results.
For offline processing is used VDI-offline software which can process measured and stored data. It provides an extended set of graphical results based on data measured and pre-processed by VDI-vision. VDI-offline also provides a complete set of numerical parameters in tables.
The measured subject is connected via the battery-powered BioSDA09 acquisition unit, which acquires the data, digitizes it and sends it to a computer equipped with the VDI-vision program for further processing via an optical communication line.
