Abstract
Electric fields A, B and C are inputted to an antenna , and corresponding digital values AAD, BAD and CAD obtained from an A/D converter are stored in memories A , B and D , respectively. An operational circuit obtains a non-linearity corrected input power level conversion table from the input power levels of the electric fields A, B and C and the corresponding digital values AAD, BAD and CAD, and stores the obtained table in a memory C . The electric field C is the electric field under which the receiver circuit is not linearly operated. A controller reads out the input power level at the time of input of each electric field from the memory C , and displays the read-out input power level on a input power level display . Thus, adverse effects, on linearity, of saturation caused by high input power level electric field input to an antenna or of noise at the time of low input power level electric field input are improved.
