Well yes, that's what the photo is above - the actual response curve of a tuner.
I connected a sweep generator to the antenna terminals with proper termination and connected my scope to a test lug they provide on the tuner. It's all explained in the alignment instructions. Any decent scope will have enough sensitivity.

That being said, it's not something I recommend messing around with. It's very easy to screw up the tuner and they rarely need adjustment.
