The object is to provide a measurement system of communication device that makes it possible to reduce costs and spaces for measurement. A CPU 13 gives a signal generator 4 an instruction to output a signal for measurement. A signal generator 4 outputs the signal for measurement into which a predetermined audio signal is modulated, in accordance with the instruction. A reception processing section 11 performs predetermined reception processing including demodulation processing for the signal for measurement, and outputs the demodulated signal. A low frequency analyzer 6 measures characteristics of the demodulated signal outputted from the reception processing section 11 , and outputs the result of measurement to the CPU 13 . The CPU 13 displays the result of measurement on an LCD 12 , and adjusts the characteristics of the reception processing section 11.
