Before making measurements, adjust all coils in accordance with the following procedure : 1. PIF VCO coil : Set pin 34 (L/BG) to ground. Input SIG1 to Tp8 (PIF Input). While observing Tp1 (AFT Output), adjust the PIF VCO coil. Find the area at which Tp1 voltage changes abruptly. Within this range, further adjust the PIF VCO coil until Tp1 voltage reaches 4.5V area voltage. 2. SIF VCO coil : Set voltage of pin 34 (L/BG) to 5V and pin 23 (MODE SEL) to ground. In no-input state, set Tp5 (AGC Filter) to 3V, and measure the Tp22 (S APC FIL.) voltage (Vp1). Then remove 3V from Tp5 and input SIG2 to Tp7 (B/G SIF Input).
