Not only on this level. On any level. There is no such thing as a perfect scope that makes everybody happy.

I used my scope almost every day and every day, I said to myself, damn guys, the potentiometers |O
Even on the low cost DS1054Z, the potentiometer are much more pleasant to handle.

I would bet that none of the mentioned scopes or any other somewhat serious digital scope of the last twenty years actually had potentiometers build in. Even twenty years ago, all the scopes on the market used rotary (quadrature/incremental) encoders.

That's true but not really an argument to buy a Rigol DS/MSO7000 which doesn't even have a 1Ghz option.
--- Quote from: jemangedeslolos on February 21, 2020, 08:32:18 am ---I expected a lot from the new SDS2000XPlus, but it comes with shared vertical control, "only" 2Gs/s and the low cost model comes with standard probes ( and no auto sensing probes ).
--- End quote ---
Actually, only the top end model "SDS2354X Plus" comes with proper probes - and costs nearly as much as the Siglent SDS5034X (actually more if you consider the free options you get with the SDS5034X ). Anyway, this being cheap on the probes is really ridiculous.
--- Quote from: jemangedeslolos on February 21, 2020, 08:32:18 am ---I know that the SDS5000X and the SDS2000XPlus will be better in certain cases....but for a little less than 2000 € I bought yestreday a MSO7014 brand new.
--- End quote ---
Which is bout half of what it costs normally (3806.81€ including VAT). So while saving money always is a nice thing, it doesn't really make sense to compare a bargain to regular prices of other products.

So stop making me doubt >:D

In some way this reminds me of my PC repair shop days. People would come in with crappy PCs which didn't work well due to bad hardware. So the first diagnosis: you bought crappy hardware, live with it. Can tweak it a little but half your PC needs replacing if you want a machine which works fine. After making do for a while they usually came back for the hardware swap. So money going into my pocket again. But in the end these people ended spending more money on their cheap PC compared to buying a good one.
I'm seeing a similar pattern here. People keep swapping between scopes and brands and have to lose money in the process.

When we listen to you, we have the impression that the oscilloscope is unusable, unreliable and crashes like a crappy PC....but it is not the case.

Then why did you go through (IIRC) 4 oscilloscopes in the past year? >:D How much money did you spend in total?

You are not 100% wrong ;D
I bought severals scope in the past four years....but I need 2 scope, one at work and one at home.
I started my business in 2015 and I have to say that I was not as crazy about test equipement as I am now.
At that time, the scope that were in my budget were based on old platform with limited CPU power, less capable regarding protocol decoding, auto measurement or math function for example.
And no one had a touch screen.
When i saw the progress that was made at this level, I wanted to change before my old scopes became unsaleable or completely obsolete.
But you can be sure that when my business will be more peaceful and that I will have more money, I will buy a Keysight.
For the moment, I have not encountered big troubles during my development because of my Chinese scope.
I am certainly less competent than you and work on less complex things which explains why I can live with 2000€ oscilloscope when you need a >6000€ one.

You are right, I meant rotary encoder. But that doesn't change the fact that they are cheap on the Siglent and much better on Rigol scope.
It sound ridiculous but that matters to me, just like the fan noise....and to be honest, it is better on Siglent scope.
And regarding the price, sadly, it make sense to me. I hope one day It will not.
I don't know why the price was so low this time, it is a brand new device. For me and my needs, I think it is hard to have a better price/perf ratio.
And last little info, the MSO7000 has no 1Ghz option you are right, but hacked to 500Mhz, it has a BW >800Mhz which will be enough for me.

Of course a ~50% discount can change the perspective about a product, but this doesn't really matter for those paying the full price.

Well, that's debatable I guess. Maybe it will give a step response that looks like 800MHz bandwidth, but that's not necessarily the same thing.

I never said that my choice was the best whatever the scenario.
I had never been interested in this scope before coming across this offer.
After taking a closer look, at this price, I thought it was one of the best options for the poor man that I am.

I think Sighound36 has all the equipment necessary to make this measurement for us.
I believe he use two method to measure the BW and he found 850Mhz with flat method :)
