Alignment Instructions
At a video carrier input level of
V
23/24
= 4 mVrms,
f
P/C
= 38.9 MHz, and a superimposed AGC
voltage of
V
3
= 1.5 V, the demodulator tank circuit is preliminarily aligned until a max. video signal
14 Vpp is obtained at the video output. Any suitable video test signal can be used for modulation.
The AGC voltage
V
3
is reduced until the signal is approx. 1 Vpp and the max. video signal is
obtained when fine-aligning the demodulator tank circuit. The alignment is not critical due to
relatively large bandwidth of the demodulator tank circuit. Fine-tuning to intercarrier
S
/
N
, differential
phase or 2T-pulse characteristics is possible.
