Abstract

PURPOSE:To securely and easily decide the quality of a television receiving circuit to be inspected by respectively inputting a high frequency television signal to a television receiver to be reference and the television receiving circuit to be inspected, switching video signals outputted from both circuits, simultaneously projecting them and comparing both screens. CONSTITUTION:A television signal 23 is inputted to the antenna input of a television receiver 1 and a television receiving circuit 2 to be inspected and an IF output signal of the circuit 2 is inputted to a chassis 3. From the chassis 3, a video output signal 13 and a horizontal synchronizing signal 14 are outputted. From the video output circuit of the receiver 1, a video output signal 15 is outputted. During the period of a pulse width T (T1+T2) inputted to a reset input pin 19 of a switching circuit 9, on the screen of the receiver 1, an image B of the receiving circuit 2 and an image A of the receiver 1 to be reference are simultaneously projected. Accordingly, defective development can be easily discriminated by visual observation and the quality of the receiving circuit is decided without fail.
