The invention relates to a device for analysing radio-frequency systems. Such a device comprises means for detecting radio-frequency electromagnetic signals, and means for determining at least one analog property of the radio-frequency signal received form the reader. According to the invention, the device further comprises means for producing an electromagnetic excitation signal in order to excite the radio-frequency tag, and means for determining at least one analog property of the return signal received from the radio-frequency tag. The device permits the effective analysis of RFID systems, for example, in system-installation and error-searching situations.
