I suggest to avoid 50-60 Hz and 0...100 Hz range, because some oscilloscopes have amplitude distortion at such frequency.
I think 1000 Hz will be good enough. So, the time interval between steps should be about 1 millisecond.
But anyway, proper 50 Ohm termination is a better and much easier way to get proper amplitude measurement. :)

I have a Rigol and it works correctly, and not like your Siglent. :-DD

yeah, but who knows, may be Rigol has another issue... :D

Of course there is nothing perfect.

I added some pictures on how to connect signal generator to measure amplitude properly.
This is strongly required if you want to know real amplitude value instead of random. Don't confuse, this is not just a decrease in amplitude by half. This is the only way to know real amplitude with no random scale factor.
