Abstract

A radio communication analyzer can test a radio device under test which corresponds to one of a plurality of types of digital communication systems in accordance with the digital communication system to which the radio device under test corresponds. The radio communication analyzer includes a modulation section, a demodulation section, a modulation/demodulation processing section, and a control section. The modulation section has a first rewritable memory, and converts modulation data indicating the contents of a first test signal to be transmitted to the radio device under test into a digital modulated signal by executing a program written in the first memory. The demodulation section has a second rewritable memory, and generates demodulated data from a second test signal received from the radio device under test by executing a program written in the second memory. The modulation/demodulation processing section has a third memory. The modulation/demodulation processing section generates data to be input to the modulation section and processes the demodulated data obtained by the demodulation section on the basis of a protocol for the digital communication system used by the radio device under test by executing a program written in the third memory. The control section reads out program data corresponding to the respective types of digital communication systems and stored in a storage unit and writes the program data in the first, second, and third memories.
