I like Shariar's videos, in fact he's the only reviewer who's videos I watch regularly and completely, and the reason is that his videos are at a level of experienced professionals.
It depends on what you mean by a professional.
Someone with a somewhat solid EE/RF background which is used as part of the dayjob to some extend. That doesn't necessarily mean a RF engineer.
What I find a bit bewildering is that I seem to be the only person who thinks that none of the main bloggers ever reviews a spectrum analyser properly from a technical point of view. i.e. they don't do any of the classic formal tests.
You're not, but I don't really expect that to find in a video review, which I see more as a quick hands-on assessment in terms of usability/handling and build quality, and that it is assumed the instruments is compliant with its specifications.
I think that Shahriar's videos are aimed towards the typical 'casual' user of a spectrum analyser in this class. That's fine but some professional users of a spectrum analyser would (hopefully) want to see some formal/classic tests to see if this analyser can qualify to sit on their bench. However, most potential users of this class of instrument won't know (maybe won't even care that much?) if the analyser display is telling the truth about the spectrum it is attempting to measure. So maybe they don't want to see formal testing/comparing. They just want to see the features it offers and how easy it is to 'drive' it.
I believe the latter is true, plus there's a certain entertainment part that people seem to expect. I wouldn't put it in the same class as a professional product evaluation, which is what you seem to expect.
Also, reviewers have to be generally careful as to how much negativity they can or should express, because no matter if justified or not, if a manufacturer sees critique as unjustified then they won't provide further stuff for reviews. It's the same in many other areas. This means you have to take video reviews with a large grain of salt.
I'd love to see real thorough product assessments but we're unlikely to get that from self-financing video reviewers on Youtube.
But if the analyser WAS reviewed properly from a technical point of view they would at least be able to see if it was a contender for serious use professionally.
The thing is that for serious use performance usually isn't the only criteria, in fact in my experience it's pretty much just half of it, the other half being stuff like reliability, maturity (an area Siglent has traditionally struggled a lot!), support (now and in the forseeable future) and so on. That means that even if this was the SA with the best RF performance in its segment I can't see any of our labs even considering it.
Like I said, I suspect that Shahriar's videos are tailored towards the advanced student/hobbyist. They definitely are not aimed at a professional RF engineer for example. There's too many classic/basic tests missing.
Finally someone who is on the same page as I am! Thanks for backing!
Eh, what?

Didn't you just argue for more beginner's content in Shariar's videos while G0HZU was pretty much talking about the opposite (examining the RF performance further)?
