PURPOSE:To easily perform a correction for the loss or gain from a received input defining point up to a received electric field detection means even if they are deviated from those at the time of an adjustment. CONSTITUTION:The loss of a signal transmission line 8 exists from a received input defining point 100 to the input terminal of a reception part 1. By the reception part 1, a level adjustment circuit 2, an analog/digital detection circuit 3 and a ROM 5, the digital signal S 16 of the value corresponding to the signal intensity (received electric field intensity) of a reception signal S 10 in the received input stipulated point 100 when no change exists in loss is generated. From a dip switch 7, the loss or gain correction value of the line 8 is inputted. This correction signal S 18 becomes the address signal of a ROM 6 and generates the digital signal S 17 corresponding to the correction value. An adder 4 adds a digital signal S 14 and the digital signal S 17 and the correction of the received electric field intensity in the stipulated point 100 is performed. |
