AFAIK there are only a few resellers here [...]
Beta testers are many more [...]
It does not matter to me whether someone is making money from customers by selling Siglent products, or is getting money and/or free stuff from Siglent directly. If the result is that they feel loyal to Siglent, and hence don't give balanced advice here but act as Siglent advocates, that's what I need to know and what I refer to as salesman behavior.
You could of course research members posts and particularly their topics to seen how they fit into this forum. [...]
As a side note, one does not have to actually read the posts. It is sufficient to observe who's thanking whom on a regular basis to identify the members of the "Siglent mutual back-patting society".
Those that can be bothered to do the research can easy discover these members that for whatever reason chose to fly below the radar rather than be attacked for brand preferences.
Why would it be more desirable to be perceived as someone with a brand preference (and a material interest) who is not upfront about it?
All of that is a moot point.
Problem is not who works for who or do they wear it on forehead.
Problem is staying on topic and dealing with facts.
For instance, I publicly say I prefer Siglent scopes because until now, trying all kinds of scopes, I prefer LeCroy type analytic scopes and Siglent makes something similar and is clearly more affordable. And they have excellent quality, and are decent company. I was Rigol user first, and I gave up. I was very interested in DS7000 at the time and eventually gave up, for instance. I also think Siglent is way better in bug fixes, adding features. Evidence is all there.
So yeah I'm biased towards Siglent because their "way" is closer to way I think.
Martin tried to make a comparison thread between cheaper SDS1104X-E and bit more expensive DHO800. They are in similar price bracket of entry level "not a toy" scopes, where DHO800 is sort of a "new generation DS1000Z".
And Rigol marketing and fanboys started victory lap of "game changers" etc etc.
But if you do cold fact based analysis it is not so clear cut. Especially because Rigol made spectacularly horrible release of what are basically release candidate products. Software for whole series was released in alpha stage, DHO900 violates Nyquist if not run in special combinations of channels/MSO etc...
So Martin being a scope person, buys a DHO800 (with his own money ) out of sheer curiosity. He also have access to dozen of other scopes (Siglents and LeCroys) so he can compare it.
And all we get is, well, you saw what we get..
In this topic it was not any of "Siglent fanboy club" that sabotaged the effort.
If I was not persistent, there would not be any good information about:
- segmented mode an its usage with measurements and decoding (note THERE IS NOT a word about it in manual. According to Rigol that is not possible)
- Details of statistics
- Some FFT data pulled from scope that circumvents closed and nontransparent "trust us there is a bump here" FFT on scope.
Martin also showed
- decoding in a table,
- statistics in a table,
- how you can arrange windows in all kinds of ways not only vertically (also not something you could learn from any Rigols docs).
All of that actually puts DHO800 in more positive light, better than what could be gleaned by looking at their own marketing and docs.
And all of that effort by "Siglent fanboy club" was actively disrupted by people who actually have DHO800.
Animosity and hate even if you say good things.
Which does not matter but facts.
