Measuring RF circuits response using software defined radio system

Abstract

Four basic methods for measuring RF circuit frequency response were implemented and tested on the popular software defined radio system based on popular GNU-radio software package and on the Ettus USRP hardware. Properties, advantages and disadvantages of this solution were studied and are described in this paper. Using the proposed platform for measurement is interesting, because the equipment needed is much cheaper than standard test tools and can be used for educational or research purposes, where long time or intensive measurements was needed.
