WOW just WOW ! :o :clap: :-+
DSO's are shit at XY mode, yeah right ! :-DD

Gotta love it when digital finally is able to do what analog could do all along. Just sayin' ;)

Sure but this shows the days of analog scopes are done.
Why even would anyone still own one when a DSO has so much more to offer. :-//
Nearly 15 years back I could see the writing on the wall for CRO's even with the old lunchbox Tek DSO's and way before I'd even heard of Siglent.
My, haven't things come a long way in just a few years.....

I found one trick that made graphics rendering more consistent is to feed a fast waveform (e.g. 1MHz sine wave) to a spare input as the trigger source, to force as fast an update rate as possible on the scope. This ensures as little dead time as possible between triggers, and that the waveform update rate is consistent.
Also, this avoids situations where the graphics is just a dot, or a vertical/horizontal line, the waveform does not update unless in auto trigger mode.
The improvement in graphics quality from this arrangement kind of makes sense, as XY mode on analog scopes is just a completely continuous vector plot without triggers. So by actively forcing the waveform acquisition to trigger unconditionally with as little dead time as possible, the graphics rendering would be the closest to what an analog scope could produce.
By feeding a 1MHz signal from the scope built-in AWG to the external trigger input, I could achieve 46.9 wfm/s , when the timebase is set to 10k sample memory, 500kSa/s, 2ms/div. The shroom on my screen looks really nice.
Side note 1: Listening to the original quality audio tracks with earphones is a trippy experience, the data modulation audio pulses hits your ears like no other music. I imagine this is what the life of a RF demodulator sounds like.
Side note 2: A discussion on analog graphics rendering capabilities of digital oscilloscopes, what a time to be alive. ::)
