Abstract:
1. An arrangement for calibrating a software-controlled vector network analyzer (VNA), comprising: a vector network analyzer (VNA) configured, in a calibration mode, to treat a connected calibration component as a measuring object, and calculate error terms from actual measured values and characteristic data of the connected component saved to a memory of the VNA and, in a measuring mode, to output measuring results which are corrected for connected measuring objects according to the error terms; a set of calibration components configured to connect to the VNA, each calibration component comprising a transponder with 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; and a wireless interface for wirelessly communicating between the VNA and a respective one of the calibration components connected to the VNA, the wireless interface being configured to read at least the non-changeable data from the respective calibration component and increment the stored number of the calibration processes performed with the respective calibration component.
