If i understand this right, you pic a med point like 44mhz, then sweep that with a 10mhz sweep (34-54) and watch the detected signal on the scope.
Looking for the correct IF shape, using markers to see where the curve is.
At least that is the way I understand it. I have attempted alignments on FM receivers using sweep gens and scope.
I have had a hard time getting results to look right, dont know if its me or my equipment or both.
Anyway I will press on and post my results.
