This diploma thesis focuses on the design and implementation of an emulator of RFID protocols in a software defined radio. The designed emulator operates in the UHF band (860 MHz – 960 MHz). The main goal of this design is a very fast measurement of power characteristic of tag. The proposed solution is based on implementing the transmitter controls directly into the SDR. Thanks to this solution a reduction of delay between measurements occur compared to the conventional concept, when the transmitter parameters are controlled by the hosted PC. In this thesis, suitable platform based on research is chosen for implementation and also a concept of design is proposed and described herein, which is based on implementation of time critical algorithms directlyinto the software defined radio’s FPGA. The proposed solution was implemented into selected platforms and its functionality was experimentally verified
