1. Receive "PAL COLOR BAR" signal.
Signal Strength: 54 ± 1dB_V (75 ohm termination)
2. Connect the oscilloscope to TP53 (Tuner's AGC
Terminal) as shown in figure 3-1.
3. Select "RF-AGC" item in the Adjustment Mode.
Adjust the "RF-AGC" bus data to obtain the Tuner
output pin drop 0.1V ~ 1.0V below maximum volt-
age.
4. Change the antenna input signal to 63 ~ 67dB_V,
and make sure there is no noise.
5. Set the RF AGC to 0 - 6 V with no saturation with
the waveform.
6. Turn up the input signal to 90 ~ 95 dB_B to be sure
that there is no cross modulation beat.
