PROBLEM TO BE SOLVED: To provide a radio call signal monitor which monitors radio call signals only so as to confirm the radio call signal including a data speed in the case of monitoring the radio call signals with a plurality of data speeds. SOLUTION: An interval between change points of a level of a radio call signal is an integer multiple of a period of any data speed of the radio call signal and the number of bits and the data speed are identified based on the value. A change point detection means 11 detects a change point of a level of the radio call signal. A bit information identification means 14 reads the interval between change points measured by a change point interval measurement means 13 and a level of the radio call signal while the change point interval stored in the storage means 12 is being measured to identify the data speed, the bit number and the logic of the radio call signal. A radio call signal analysis means 16 receives the data speed, the bit number and a logic value via a serial transfer means 15, analyzes and displays them according to a radio call signal format. |
