Yes, unless stated otherwise lowest signal needed to get the response. And if there's AGC in the set you generally disable that by applying a fixed voltage. I'm talking about TV's, AM radio on the other hand you can usually get away with monitoring the AVC line for strongest signal while adjusting the IF's.
That sine wave distortion you show in your last post, believe it or not that kind of thing really won't bother for alignment. We need to remember that the RF is only the carrier for the modulating sound and video information, so the important thing is the response of the video IF amplifiers, and for that you need the generators frequency calibration to be accurate.
