description PROBLEM TO BE SOLVED: To reduce a display error of input level indication caused by a difference from reception frequencies. SOLUTION: A mapping function is generated by correcting an AGC(automatic gain control) value of a signal with a prescribed frequency or over at which the AGC value is largely changed depending on a characteristic of a high frequency circuit block by a prescribed value and stored in a memory 16. When a reception frequency at input level indication exceeds the prescribed frequency, after the AGC value is corrected by the prescribed value, the indication level of the input signal is calculated by the mapping function.
