PURPOSE:To speed up an adjusting speed and to receive all receiving channels in high sensitivity by constituting the receiver that set conditions of tracking adjustment are stored to all receiving channels so as to be read out. CONSTITUTION:A test signal is applied to an antenna 1 through an attenuator 1 and inputted to a harmonic amplifier 2. The test signal and a local oscillating signal are mixed at a mixer 3, and an intermediate frequency signal generated from the mixer 3 is amplified at an intermediate frequency amplifier 5, detected by a wave detector 6 and this detected output is outputted to a detection output terminal 19. A part of the detected output is applied to an S/N detector 7, a detection controller 8 is operated so as to maximize the S/N and a digital signal generated by sweeping a digital code generator 9 is applied to a D/A converter 10 through a memory 11. This operation is done for all channels. |
