What are you implying? Some tricks or manipulations on my side? Are you questioning my integrity?
No second thoughts, and no cause to get defensive -- just the two questions mentioned earlier. Please take them at face value.
As I tried to explain before, it would make sense to me that the scope can draw traces on the screen at full resolution (only) if it gets the data to be plotted directly from the 12-bit capture buffer, under the circumstances described in my questions. So I would like to understand whether that is the reason for the different appearance of your screenshots vs. others I have seen.
I can obviously try this myself once I have an SDS HD scope. But the thing is that my decision whether to get an 800 or 1000 series scope will depend on what I can expect to see on the screen. So I would much prefer to understand this upfront, rather than create extra hassle for myself and Batronix by buying one model, then potentially having to exchange it.
I don't think the answer to those questions can be gleaned from the screenshots themselves. And unless I overlooked something, I don't think you have answered them yet. Pretty please?
Is it maybe that a single capture gets rendered differently -- plotted directly from the full-resolution data buffer? Did you capture these traces in the screenshot in Single mode; or did you stop the acquisition and then shift the displayed time window so the screen got redrawn from the buffer?
I'm not being defensive but wanted a clarification. We are both conversing in what is, to us, a second language. Better verify than presume...
All I did was start the scope, attached 1MHz squarewave into it, chose that timebase at random and you see results.
Plain as that.
I tried in both Stopped and Single. Made no difference.
I do not know why their images are different. Maybe they (them) cherry picked images to illustrate point they wanted to prove?
Or maybe simply, as I did, chose some random settings that resulted in those images. I don't know what they did.
You will have to ask them. I didn't answer that question , because it is not addressed to me.
I told you what I did, which is all I can answer. Sorry.
I'm not disputing their images.
I simply wanted to investigate statement that kept being repeated that 1000xHD draws 2 vertical pixels ALWAYS, and that 800xHD will probably too.
Well, now we know 800xHD for sure does not draw 2 vertical pixels ALWAYS.
That is all.
That is my data point. I leave further speculations about rendering implementations to others.
I personally didn't notice it until this discussion broke out. I had to use loupe to actually see it. That is how "big" problem this is in real life (pun intended).
I find implementation fine in normal work and will prefer not to waste more time on it.
There are many more interesting things (for me..) on the scope to investigate.
You guys have fun with this, if you like.
Best,
