| Abstract: | A portable tester is presented in this paper, which can be utilized in detecting RF characteristics of RFID(radio frequency identification) system. The operating frequency is measured by pre -frequency division method, the intensity of radiation field is measured by demodulation method, and the input power of the antenna is measured by directional coupler method. The data acquisition and processing is computed by chip microcomputer. The measurement accuracy is in good agreement with the requirement of detecting railway carriage number identification system. |
