Characteristics

Alignment Instructions
At a video carrier input level of
V
1/2
= 4 mVrms,
f
PC
= 38.9 MHz, and a superimposed AGC voltage
of
V
22
= 1.5 V, the demodulator tank circuit is preliminarily aligned until a max. video signal
V
11pp
is
obtained at the video output. Any suitable video test signal can be used for modulation. The AGC
voltage
V
22
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.
