Transportable AD box for comparative measurement

The evaluation of testing systems designed for dynamic testing of ADCs or AD modules is very difficult, because there is no reference digitizer or testing method with a significantly higher precision, and only comparative measurement comes into consideration. Therefore, a transportable highly stable reference AD box convenient for comparative measurements was designed, and the first prototype was realised. The whole design was made with a view to high stability and internal disturbance minimisation. To achieve greater flexibility, a modular solution was proposed. The basic structure and the realisation of single modules are described
