As a side note, we actually do a sweep on the InfiniiVision 3000T and 4000 X-Series scopes very similar to what a standard FRA or VNA would do. We built it for power supply testing - namely control loops response and PSRR. We plot both gain and phase up to 20 MHz (the bw limit of our "WaveGen"). Johnnie Hancock did a video on it recently, too: http://bit.ly/2dfGaLY

You probably aware your hijacking this thread, like this, right?  ;)

Sorry, I'm not trying to derail the conversation. I rarely push things like this, but I thought it was relevant to the discussion in terms of the validity of using a scope and function generator for frequency response measurements.

Thanks for bearing with me! :)
