--------------------------------------------------------------------

And many of the same features offered in SDS1004X-E.....
Bode plot
MSO option
AWG option
WiFi option

Waveform search
Navigate/History/Sequence
1Mpt FFT
Web browser etc etc

But plus:
2 GSa/s sampling
28 Mpts memory
50 ohm inputs

What are the main differences for the 1000X-E?

You need split thinking to two separate pathway.
SDS1002X-E
SDS1004X-E

Even when SDS2xx2X-E is 2 channel it is not evolution of SDS1002X-E

It is better imagine it is more like half channel SDS1004X-E mutation- evolution (lot of similarities except BW samplerate and due to double samplerate memory is doubled so it is proportionally same.)

It is - imho - not any kind of big jump to up or side. Only more choices for customers  in the current product range at approximately the same level.
 
SDS5000X ... it is totally different case. It's proportionally big step out of the current product portfolio.

I wonder why this is only offered as a two channel, and not four channel?  How much more popular are the two channel units vs. the four channel ones overall?

So, it's a 1004 with 2 channels, more BW and memory. Other features are the same, so it takes advantage of their maturity (or lack of). I bet it has network security issues, bla, bla, bla...   

I don't find it bad. It widens the entry portfolio.

I'm waiting for the SDS5000 but now there are also the Rigols...

This ^ and at a good price too, a 2ch 200 MHz 2 GSa/s DSO.......under $650 ! 

[tv84]

Or 350 MHz...

Apart from everything else, I can assure you that a 100MHz square wave looks very different on a true high bandwidth scope from what has been shown in the MSO5000 hacking thread.

[rhb]

With a 100 MHz square wave there isn't much time for the ringing  from a fast edge to die down. 

IMHO Leo Bodnar's  10 MHz, <40 pS rise time square wave pulser is more appropriate for torturing scopes into confessing.  I've subjected an MSOX3104T and an RTM3104 to it.  The "1 GHz" Keysight had a 436 pS rise time with 7% overshoot.  I sent it back.  An RTM3104 demo unit had a 350 pS rise time and 3% overshoot.  Until I installed the 1.300 FW update.  At which point it had 10% overshoot.  Reverting to 1.100 did not restore the 3% overshoot.  I shall let the reader draw their own conclusions.  I was quite shocked as my experience calibrating a Tek 465 led me to expect no more than 3% overshoot. So I went from delighted to horrified in a week.

I'm very skeptical of the Rigol DS1000E/Z  hacks as I've never seen any step responses.  Logically with a DSO, you build it, then you measure the AFE performance and apply a correction for component tolerances.  After that, if you want software BW updates you apply a 2nd digital filter.  The 1st filter is calibration  for that instrument.  The 2nd filter is a license option.

I recently bought a refurbished 485 on eBay.  I've not yet done the full cal procedure which is *very* long, but I plan to adjust it to under 1% overshoot, rise time be damned.  I don't care if it's only  300 MHz  at -3dB.  I want to be sure that any ringing is the DUT or user error.

My LeCroy DDA-125/LC684DLX has a <250 pS rise time and 20% overshoot. I plan to correct that with sensible anti-alias filters.  750 MHz for 4 channel mode and 1.5 GHz for 2 channel mode.

My Rigol DS1102E is 3% and my Instek MSO-2204EA is 5% both with rise time = 0.35/BW.  And an Instek GDS-2072E hacked to 200 MHz exactly matches the 2204EA both at full BW and at 100 MHz.

There's a long thread about Leo's pulser  here:

https://www.eevblog.com/forum/projects/yet-another-fast-edge-pulse-generator

with lots of screen shots on a wide variety of instruments.  And each unit comes with a printout of the step response on a very high BW scope.  It beats the pants off the Tek 106s  I bought to calibrate my 465 and Dumont 1060.

[MrW0lf]

Just a word of caution for generic reader - if plan to poke actual DUTs with x10 probes then it may make sense to get probe => BNC M & BNC F-F adapter and stick Leo's pulser on the end of probe [possibly with additional 50Ω load], not directly on scope BNC with ext or int 50Ω.

[Performa01]

EDIT: Be aware that this is from a high bandwidth scope and of course not from an SDS2000X-E!

I thought I should back up my claims by showing an example:


Square 100MHz_Z2ns+FFT

This is a 100MHz square wave with <<100ps transition time.

Main timebase is 100ns/div in order to get a sufficiently detailed FFT from DC to 2GHz.
Zoom timebase is 2ns/div in order to get a detailed Y-t view.

Automatic measurements:
FOV = Overshoot after a falling edge.
ROV = Overshoot after a rising edge.
Rise & Fall times are not accurate because of limited scope rise time and also time measurement resolution limited to 20ps at that timebase.

Hello!

That is a nice square. What is the generator if I may ask?

And scope handles it quite well.. Frontend looks very decent here....

Take care!

[JPortici]

was that the 5000? nice interface.
Looks like someone actually learned from their masters 
The layout, the font sizes, the proportions, the choice of colours

no 4 channel model because?

Exactly what I've asked.
You might guess by the front panel layout, one is coming.....
About that, I have zip info. 

[oewean]

Been told there is not going to be a 4 channel.
But who knows, if there is a demand?

Are the MSO/LA signals available via LXI/SCPI?  Is serial decode still restricted to just what is on screen?  The 2000X series scope is a bit hobbled by the fact that the logic analyzer (digital signals, serial decoders) is not exposed via SCPI.  And serial decode is limited to just what is on screen.

Depends on how you use it.....use the Zoom mode where you can have seconds of data stream on the main window and just a tiny portion in the Zoom window where you can still scroll to any of the packets in the main window.

The 2000X series scope is a bit hobbled by the fact that the logic analyzer (digital signals, serial decoders) is not exposed via SCPI.

Only Decode as outlined above. Currently none of the Siglent DSO's apparently are able to access Decode via SCPI.
The same applies for Bode plot in the SDS1004X-E models as there is no SCPI command set to enable that.
It will require firmware changes to get  the SCPI command sets installed.

Maybe I'm missing it and it's in plain sight, but what is the sample rate on the digital channels?

Thanks for sending that.  It has been a while since I looked for an update to the SCPI manual.  I also see that I have missed a couple firmware updates in the past year.

It says "D[X] — Digital channel. Only valid for SDS1000X-E series."  (Page 179, WAVEFORM command.)  Yes, one can control the MSO, but the digital waveforms cannot be retrieved from a 2000X for external analysis.  This means that only the 4 analog waveforms can be used in tools like sigrok -- and, as a 2000X owner, that makes me sad.

But that's certainly good news for the 1000X-E users.  And hopefully that means it works on the 2000X-E series as well.

It's in the datasheet: P3 and 14.
Maximum waveform capture rate up to 1GSa/s, Record length up to 14 Mpts/CH

The 16 digital channels are provided with an external module, the same as used for SDS1004X-E models, the SLA1016 that connects into the front Sbus connector.
