Hi. I have an idea that I don't know if it works in practice, and would like to ask if anyone with experience can chime in. It's obvious that you can't align a high end tuner with very low distortion with a generator that doesn't have similar distortion specifications, preferably lower. However, what about if the specs of the generator are just a tid bit higher, for example, a tuner with 0,02% distortion and a generator with 0,05% ? Using a spectrum analyzer (in my case I plan to use PC based software with a high end sound card), even if there is distortion present that is not originated by the tuner, one would still be able to lower distortion up to spec because the distortion caused by the generator is in the same order of magnitude of the tuners, provided the spectrum analyzer's scale and graph is up to it. Totally different scenario from using a generator with say 0,5% distortion, which is not so uncommon.
Is my theory correct or do you really need a 0,01% distortion generator for this type of thing ?
Thanks to all.
