That is because the Keysight lover entered the room. Nothing to be happy about that because these guys have such a short memory that they incapable of remembering jokes
That's the thing, isn't it? There are a few people here who can't distinguish between normal conversation and endlessly obsessive disfunctional behaviour. They think anyone else is how they are and what they're doing somehow normal. I don't think you understand how fed up most people here are with thread after thread being barfed full of the same inane drivel. Any sensible discussion is long gone because the sensible people quickly move on. There's a wealth of knowledge which won't partake in these conversations because of the bad behaviour of a few. What's left is the same hot garbage we see in every thread. Newcomers in turn are missing out both because a lot of knowledge is absent and because they're actively fed FUD. Not to mention their first Eevblog experience is by far the worst one to be had. It's like a toxic moat keeping people out.
I don't know why Dave puts up with it, but maybe he's decided his time is more valuable. If it were up to me the two or three usual suspects would've been booted long ago. Any useful posts are swamped by an avalanche of disappointment and bile.
I think a relative newcomer like myself needs to spend some time reviewing the posts to get an idea of where the bias is. In my case a recently retired advanced technology researcher doing SOTA IC design I had never heard of Rigol, Siglent, GW Instek or others. Our labs had Tek, HP/A/KS, R&S equipment, and I had very little exposure to DSOs since at the later part of my career I was at the front of the IC design and didn't get into the labs much. So when I starting a new home lab to get back to my older "hands on" lab experience I got a couple Tek 2465 scopes off eBay and fixed them up, then a couple HP & Agilent 34401A DMMs and fixed them up, this was my comfort zone Tek & HP. Since I needed a cal reference for the DMMs I decided on the KS 34465A. I'm particular fond of Keysight having designed Indium Phosphide test chips in their 600GHz process, and know and worked with a few senior KS folks, so my KS preference.
Now it comes time to dabble in DSOs and this is when I came here looking for info to help decide back in July. I spend countless hours following all the posts on the various DSO threads, and became familiar with the bias for the various brands. After "listening" to all the arguments/discussions and such, I decided to deviate from Tek or KS and try a Siglent, ending up with a SDS2102X Plus, which has exceeded my expectations in just about every way
So without all the endless arguments/discussions on various threads I probably would have ended up with a KS instead of the Siglent DSO. Would this have been bad, heck no the KS DSO is superb I'm sure. However, I believe the Siglent is a better value for my home use since my time isn't valued now (IC design is a very expensive field and time is also very expensive), if this was for our labs while I was working then the KS would have been the choice.
Anyway, my point is that having endless discussions from biased sources isn't always bad, and if you can spent the time to review the various posts then the bias can be factored into the responses. So a savvy newcomer looking for advise on a DSO purchase should spend some time to understand the responses from the various sources.
I do agree if the arguments/discussions gets out of hand then moderation is required.
Best,
