ABSTRACT:
The object is to provide a measurement system of communication device that makes it possible to reduce costs and spaces for measurement. A CPU13gives a signal generator4an instruction to output a signal for measurement. A signal generator4outputs the signal for measurement into which a predetermined audio signal is modulated, in accordance with the instruction. A reception processing section11performs predetermined reception processing including demodulation processing for the signal for measurement, and outputs the demodulated signal. A low frequency analyzer6measures characteristics of the demodulated signal outputted from the reception processing section11, and outputs the result of measurement to the CPU13. The CPU13displays the result of measurement on an LCD12, and adjusts the characteristics of the reception processing section11.
