That's handy. The 3563A can also do this THD calculation and I never knew!

Thank you!

I really should play with my 3561A, I haven't used it since I did the videos fixing it!

They sure are handy, at least for the type of work I do (mostly audio). Having the FFT display that calculates thd on screen on a device with 1MOhm inputs is nice, for tracking down distortion and noise between amplifier stages etc. Never been a fan of the FFT mode on any of my regular scopes.
