ARRANGEMENT FOR CALIBRATING A VECTOR NETWORK ANALYZER

An arrangement for calibrating a vector network analyzer (VNA) is substantially secure against operating errors and offers cost-effective calibration by connecting calibration components. Each calibration component includes a transponder and a non-volatile memory which contains, as non-changeable data, at least the type of the component and an individual identification number and, as changeable data, at least the number of calibration processes performed with this calibration component. The VNA includes a wireless interface for reading at least the non-changeable data of a respective calibration component and for incrementing the stored number of the calibration processes performed with this calibration component.
