Alignment Instructions
At a video carrier input level of
V
1/16
= 4 mVrms,
f
PC
= 38.9 MHz, and a superimposed AGC voltage
of
V
4
= 1.5 V, the demodulator tank circuit is preliminarily aligned until a max. video signal
V
11pp
is
obtained at the positive video output. Any suitable video test signal can be used for modulation. The
AGC voltage
V
4
is reduced until the signal is approx. 3 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.
