Siglent SDS2000X Plus

I somehow doubt the internal awg can manage 100MHz. Does it clean up in single shot? If not it's probably the source or possibly the 50 ohm termination.

[Martin72]

 Argh, you're right, didn't saw the 100Mhz

It's a display scaling artifact if the menu is visible. With the menu disabled, the waveform is clean. They need to fix the coefficients for the resampling filter. If they have one at all. It looks like they scale the waveform by culling columns without filtering.

That's what I assumed, minus it having to do with the menu. That's pretty odd.

And yes, I can just fire up a vnc viewer and operate the scope through this connection :-) No need for a web browser.

Not really. It just means they're trying to do the scaling with the least CPU involvement possible. Either there's a hardware decimation in the display path that just culls display columns (is the graticule also affected?) or they need to scale the waveform in software and try doing with as little CPU cycles as possible.

[maginnovision]

Well in many scopes I've seen they don't do anything, just draw the menus over the waveform area. It's very late and I've only seen screenshots so I didn't realize they scaled the waveform with menus open.

Hello,

I'm a new owner of SDS2304X+ become now a fully upgraded
 SDS2354 with the help of TV84 ! Big thanks to him and his patience with me.

I've check with the Rigol logic probe (from my MSO2072A) and it doesn't fit,
the connector entry is not same (not very surprising).
So need to order the probe soon...

The UI of the Siglent is very responsive, we see that we have very good quality in hands.
Now, time play with these lot of functionality...

Frex

I think I discovered the rule (or the symptom) of an upgraded SDS2000X+ becoming a 2354X+ (w/ 500MHz) or a 2504X+ model:

It's all in the S/N:     

SDS2Pxxx3Rxxxx  will turn into a 2354
SDS2Pxxx4Rxxxx  will turn into a 2504

Mine is a 4R but turned into 2354, not 2504.

There goes the neighborhood.  My hunch was wrong!

What about Hardware Version?  Mine is 02-00, Serial 3R and became 2354X

[thinkfat]

I don't think there's any other hardware version than 2-0 in the wild.

Remains an interesting mistery...

Status on Welectron: Although they did claim that they could mail a scope in 2-4 days, and each time I contracted them they said my order would ship in the next day or two. They had not shipped my order after 15 days so I requested they cancel it. Just letting people know you might not get anything quickly from them due to COVID effects or just that they are not transparent about what they really have in stock (?).

It is unfortunate because I lost my place in line at Saelig, and I did want a this scope while I was locked down at home.

[jemangedeslolos]

I never had problem with Batronix and the scope is in stock

This challenge fits perfect to you….

A fix would be indeed nice...

My experience was too painful, waiting 2 days for each question to be answered being charged and no shipment for weeks. I don't know if that is standard practice in Germany but in the US most vendors will only prevalidate your billing until they actually put the product out to you, they take the money when they effectively transfer the product to you.

Saelig without me inquiring provided me an estimate of when it would come in and already wrote me 4 emails about my order's status. They won't bill me anything until it ships. They cancelled my last order in 30 minutes via email and answered their phone in < 5 mins when I called them on my initial order that was put on backorder. I'm going to stick with them and domestic distributors. With EEVblog discount there is 1 dollar difference and no possibility of tariff. 

Times are weird, I wouldn't have normally posted it publicly as I'm fine as long as they actually refund my money in a timely fashion. But I didn't want a bunch of people in the US to have the same issue given it was suggested that they had them and it would be quick.

Someone who has this scope already.

I have looked at the manual and so on. I presume there is no way to change trace colors in any of the menus?

Maybe it is defined in the filesystem also somewhere? (Doubtful).

When you disable the menu, waveform looks better, but change the timebase and the artifact comes back even with no menu on screen

Not at this time.

I think that Siglent just changed things after the first 4R's were out.

Screenshot? I can't reproduce it. If you set the timebase long enough, there's some visible aliasing, but it's only an 8-bit ADC and 1024x600 pixels on the display so don't expect miracles.

Would be nice when siglent could follow lecroy in this case too.
Lecroy scopes allowing not only changing the colour of all traces (channels, mathfunctions, memory waveforms), they also let you change the background into white (visible in the screenshot only, of course), which saves printer colours.
Don´t know if this could be realized.

Press "Save/Recall" button => "Image Style" => Inverted

let me change Black background to White background on screen shots

[Martin72]

Excellent, didn´t recognized this before
