Thanks Bill - I want to note here that if your signal generator has a sync output, and your scope has a sync/trigger input ("EXT") it's far easier to set this up, and you'll get an even more useful/aligned display. The generator's sync output will tell the scope when to trigger, and with a bit of math on the X graticule, you can calculate amplitude vs. frequency. You should setup the generator's sweep time to match the scope's horizontal scale (total time, horizontally) fairly closely, for it to be maximally useful.
(Edit: i see you've posted exactly that technique in reply to RensePosthumus's message; using ch 2 instead of an EXT input, brilliant)

What are the results if you use the Siglent Oscilloscope in the same way you've used the Zoyi? So just using the scope, without the bode-plot functionality.
