Alignment Instructions
At a video carrier input level of
V
1/18
= 4 mVrms,
f
PC
= 38.9 MHz and a superimposed AGC voltage
of
V
16
= 1.5 V the tank circuit is aligned that way, that at the positive video output the demodulated
video signal 6 Vpp is at its maximum.
As a modulation every sufficient video test pattern can be used. Then the superimposed AGC-
control voltage at pin 16 is reduced until the video signal has an amplitude of approx. 2 Vpp. The
video signal is then fine tuned for its maximum.
The adjustment is not critical due to the wide maximum.
The adjustment can also be performed regarding intercarrier signal to noise ratio, differential gain or
2T-pulse response.
