Thanks for the suggestion.  I'll take a look at that thread.

Shariar's video, however, is the one I linked above, where he does exactly what I am doing...

Yep, well watch it again from 37.20 where Shahriar explains that changing settings will impact the normalization and he recommends once the settings are as you want then to re normalize for accurate results.

Ah yes, the dots are starting to connect.

I appreciate the patience you and everyone else has shown in helping me to understand what was happening.

Reference Offset and Trace View

Ok, here's another behavior that seems weird to me.

Can someone tell me what I did wrong here?

Here's what I did:

I am feeding a square wave at 30 MHz through a 20 dB attenuator to the SA.

Preset -> Amplitude -> Reference Offset -> 20dB
Peak -> Peak table on
Trace -> View

Then the peak values in the Peak Table seem to go nuts and the waveform disappears.

Here's a video I captured:

Sorry but using two *10 scope probes to "demo measure" with the SVA1015X's VNA function in an unpowered CB radio corpse is, well, a little "unresultful"   :palm:
This RF stuff definitely isn't Defpom's business, clicking through the menus isn't what really helps someone seriously interested in a purchase. Regarding things one doesn't feel "at home" with, better do yourself a favor and let others who are more into it do this job.
Watching this clip is a waste of time, and probably producing it was even more so for Defpom. He's got much better reviews in his channel than this one...

Cheers and no offense intended  :phew:

What I was trying to demonstrate was the filtering effects of the tuned circuits in the RF section of the radio, and the ability to see that on the Siglent, no I wasn't trying to obtain accurate and true measurements, and at no time did I say that was what I was doing.

My reviews are done in a way to try and replicate how a new user would find the gear, something that is easy enough to capture as sometimes (such as in this case) I am not an expert in its usage having only limited experience with the particular item.
