Alignment Instructions
At a video carrier input level of

obtained at the positive video output. Any suitable video test signal can be used for modulation. The
AGC voltage
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
pulse characteristics is possible.
