Description

technical field [0001] The invention relates to a calibration device and method for a radio frequency identification tester. Background technique [0002] Radio Frequency Identification (RFID) testers are widely used in the R&D, production and testing of RFID cards. RFID testers include RFID transmitters and RFID receivers. The transmitters emit the required RFID signals, and the RFID cards receive the RFID signals. , After decoding, the signal is sent back, and the RF tester receives the signal sent back by the RFID card and demodulates it correctly. Therefore, whether the radio frequency identification tester is accurate and reliable will be very important for the testing of RFID cards. So far, the country has not promulgated radio frequency identification (RFID) tester calibration specifications or verification procedures. Contents of the invention [0003] The purpose of the present invention is to provide a radio frequency identification tester calibration device an...
