Siglent SDS3000(X) / LeCroy WS3000(Z) - Anyone has one?
bson:
I'd be happy to. Just tell me how to create it.

Currently evaluating a WS3000z here.
The -z is a major improvement, the UI finally is responsive and fast. Old WS3000 was terribly slow and laggy to the point touch control became useless, now its fine.
Touch zoom on 4x5Mpts is around a second to open the zoom window, navigating afterwards doesnt have significant delay to it. Waveform update is easily fast enough (not measured exactly though), adding measurements doesnt cause much of a change, FFT performance is good too (and not restricted to small record length like Keysight).
The user interface if nice if you are used to other LeCroy devices, if not it might need some time to get used to it (just as i need to get used to a DS1054Z), but then it dows what you want it to do. Didnt really miss any features that i would expect in that price range. Segmented memory and Histroy is there right out of the box, which is nice.
In the few days i got to use it, i could not find any major problems with it. Boots quickly (~30s), around 70W and a big fan makes it really quiet. Interestingly now it says "Assembled in the USA", as far as i know the first one didnt. Maybe some final assembly work was done there as it now looks nicely fitted and the plastics dont smell nor is the metal rusty as it is all too common with siglent.
Might be the best value for a good mid range scope if you need active probe inputs. Around 3.5k€ for 4ch/200Mhz. There isnt much competition in that price segment if you need to connect some current or HV diff probes. R+S RTM3k is quite a bit more expensive, Tek really cant compete anymore, DSOX3000T also is way outdated.
BTW, old option key format too. Cant play around with a demo unit though.
nctnico:
I don't get it. Active probes quickly cost more then several $k making the price of the oscilloscope less relevant. OTOH if you use generic probes then there are many other choices and you aren't tied into a specific brand.

Depends on the situation. If your boss approves 3.5k€ per scope, thats what you get. You always get the cheapest solution that works, 3.5k scope plus 2.5k probes is less than 6k scope plus 2.5k probes. Also at least here that will mean one set of probes for half the site (and everyone fighting over these).
Generic probes: Theres no such thing as a good generic 50/100Mhz current probe. Those with external power box are terrible to use and the power box costs another 1.5k. HV diff probes, same thing, those 9v-battery powered ones are terribly slow and have really bad CMRR. Plus the HVD3106 are hard to beat in terms of HF CMRR and noise. Dont undesestimate the amount of times you screw up calculating the resulting V/div or A/div when you have to manually do it, and then having to re-do measurements because the documentation is wrong (and photoshopping the screenshots is usually prohibited as it is considered forging results).
Anyway, back to topic.
If you want me to test anything on a WS3000z i can do so on monday.

Thankx Robert.
What is the OS of these things? WinCE, linux or other?
