Hello, Sir
I've noticed that you are a happy user of a 1104x-e oscilloscope from Siglent Could you tell me, how your work looks with it? Is there something you love about it or something you hate in that scope? I am asking because I am very interested in it personally. Nevertheless, despite the not-so-large selection of oscilloscopes in a similar class (Rigol, GWInstek etc.), I still have some doubts. Mainly due to the first Performa01 user tests, when he found a lot of bugs (also hardware errors). It would be nice to hear your own thoughts from you.
Regards!

I wanted to add that Bode plots on this scope seem to work very well in their own regard. In general, I like BodePlot II a lot and the scope is still a great value.
The problems I was encountering were not really related to BodePlot II -- the plots were just a way to help view them (separate post still in progress but nearly done, sorry I'm slow!).
For reference, I'll attach a couple of plots showing a nice (expected) response across the frequency range.
For the best signal match I could make, I used a pair of new Amphenol cables and a Pomona T-adapter coming out of one AWG output, going into 50 Ohm terminators at the scope. The terminators were both bought used off ebay and I found that one of them was a bit out of spec on its resistance, so the plots reflect this difference I believe.
Plot amplitudes are Vout/Vin ratios. One plot is linear and one is log scale.
The results seem solidly repeatable as well, so as long as you're sticking with CH1+2 or 3+4, making initial plots as correction factors is straight-forward.
