Abstract
The present invention relates to a calibration method and a calibration arrangement for a RF test apparatus for testing a RF device under test. Instead, a calibration board is provided and connected to each of the cables of the RF test apparatus. A calibration board is configured to provide a plurality of connection loops by connecting the input/output channel terminals of the test apparatus one after the other with each other. This results to a bunch of different connection loops. Then a physical parameter, such as the attenuation over frequency, is measured for each of these connection loops. Since each physical parameter can be described by a single equation, this results to an amount of different equations which form an equation system. The idea underlying the present invention is that the amount of equations of this equation system, which amount corresponds to the different connection loops, is at least equal or higher than the amount of unknown parameters of the equation system. Consequently, the equation system is overdetermined and—as a consequence of that—mathematically solvable.
