But if all data points are being mapped to the same vertical line of pixels (which they must be) - and if the minimum and maximum data points are connected by a vertical line - how are possible data points in-between visibly lost? Where would they be shown otherwise[emphasis added]?
The thing is that Peak-to-Peak only considers the Extrema, and throws away the points in between. They are lost. ....
I'm not sure you really answered Marmad's question [emphasis added]. I understand what information is lost with peak detect, but not how "binning" would show anything additional [emphasis added]. There is only 1 pixel column with which to represent all the samples.
I suppose intensity grading could be used. ....
I believe I did [emphasis added]. It shows that with what Yokogawa calls 'Peak-to-Peak' you loose the time resolution (so even if the line would contain all data points in the specific sample set then still the weighting would be lost).
It appears to me that you have not answered Marmad's question, or at least,
not entirely. He asked where the in-between data points would be shown, if not in that "minimum and maximum data points...connected by a [single] vertical line". You only responded talking about the points Peak-to-Peak loses, not how binning
displays more data.Exactly, intensity grading is one way (and the most predominant method) to store the weighting. But Binning Decimation as for example used by the larger LeCroy scopes (WaverunnerLT /WavePro/9300/LC) is a little bit more complicated [emphasis added] as it just doesn't bin data points, it uses a set of algorithms to modify the binning process.
The only LeCroy documentation I can find describing 'binning' is in reference to their Math function of creating histograms - not quite what we've been discussing here. Do you have a link, perhaps [emphasis added]?
No, unfortunately not. There is very little written info (not only from LeCroy) about this topic [emphasis added].
Here you acknowledged intensity grading is one way to show more information, but said binning decimation is "more complicated". I take this to mean binning doesn't use intensity grading, or at least, doesn't
only use intensity grading. Marmad asked for more info - still not understanding how binning
"ensures that any data point ends up on the display and no information is lost" - and you admitted you could not explain it (saying there is "very little written info" and providing no links).
Interestingly, you went on to reiterate your claims about binning. It "will let you see all glitches" but causes "dreadfully slow waveform update rates". With still no links though and only your unsupported assertions of course Marmad can't help but continue to be skeptical:
LeCroy's Binning will let you see all glitches (within the limits set by sample rate etc of course), even at dreadfully slow waveform update rates that are the result of the amount of processing that is required for this technique.
Well, I'm afraid without ANY information available anywhere to suggest that this real-time 'binning' decimation to the display either exists - or - that LeCroy is using something like it - I will have to assume it's a "belief" of yours about their DSOs.
You could be 100% correct that this "third method" "really ensures that any data point ends up on the display and no information is lost." I admit I'm pretty curious about what it is and how it works. It sure is odd though that references to such an advantageous feature don't appear to be more readily available.
