Siglent SDS2000X Plus

[thinkfat]

Post by user twizla sounds like SPAM.  Did he buy the 100MHz or 500MHz model?  How come he tested both models?

Because "hack" ?

[TK]

The hack is not public and isn't the 500MHz upgrade only for 2-channel models?

[Martin72]

Hi,
It´s meant in another way - on 500M you could only use 2 ch.

[TK]

Is it possible to use channels 1 and 3 in 500MHz model?

[Martin72]

Yes,

1+2 or 3+4 you don´t have the full BW, but 1/2 and 3/4 it´s no problem.

[Martin72]

If a 5000X or 2000X plus owner can test how decoding works for long captures, it would be very helpful.

Im not really into (serial) decoding things, so could be a stupid question:

Like this perhaps ?

Yes, something like that.  I tested the MSO5000 and at least it decodes everything that is on display, even when you capture over 10,000 SPI packets.  I tested the same on the Siglent SDS1000X-E and it stopped at around 3,000 packets, so I was wondering if anything changed on the 2000X plus.

Have you seen my spi post ?

[TK]

I just saw it, so you could decode around 9000 packets.  I am waiting for my unit to arrive and will do a full test of SPI and the scope's ability to capture infrequent SPI event

[Martin72]

Measured rise-time is 650ps for Leo

Hmmm…..must repeat my measure, I got appx 800ps.

Don´t know what I´ve meausured before, now I got appx 650ps too.

[twizla]

Hi Martin72, the rise time degrades when Channel1 & Channel2 active to approx 1ns. As sample rate reduce to 1GHz. It's still very fast

[Martin72]

Hi twizla,

I know this and the first measure was taken by only one channel active.
The only difference between the two measurings are, the first was taken with a timebase of 5ns instead 1ns now.

I really recommend the new SDS2000XPlus to all interested readers.

After having it for appx 3 weeks, I would sign this.
Nice scope for the money, regardless if it´s "hacked" or not.
Some little bugs "of course", but it´s brandnew and hope is given that siglent reacts faster than rigol ( this was one of the main points to change to siglent.).

From an anonymous source, a STB3 and SDS2000X+ SPI decode screenshot.

Finally I could decode too...
And have a look, it could decode even with a timebase of 50ms....

Good, you finally got there with a few more tips via PM's. 

Now work your way through the other STB3 protocols remembering to check packet lengths and set Trigger Holdoff to suit.
The protocol trigger suite is only needed if you want to trigger on a particular part of the data payload and attempts to do that should be reserved until you are properly confident with simple decoding. This is something I have not properly mastered however others with more decoding experience might jump in if you get stuck.

[Martin72]

It wasn´t so easy like I´m used to have it at work - Main thing would be that I´m not really into data protocols - for me ( stuck in power electronics and analog circuits) it´s a "new challenge".
But I´m willing to learn...
Won´t get it too off-topic, but there are some….Ah, forget it.
Maybe I open up a new thread about the STB-3 demo board.

[tautech]

The hack is not public .......

Not officially but for the observant you can find it on the forum buried in a thread about another model.
My sources say that script works with SDS2kX+ too !

It will be some weeks before I have a 2kX+ unit to play with. 

[Martin72]

LOL 
On the other side, I saw it on Batronix, ordered immediately, got one  - And now it´s sold out.

Duh. Just as I had halfway convinced myself to not wait for Rigol to cough up a new firmware for the MSO5000...

[tautech]

Hello everybody

Welcome to the forum.

Here are a few pictures of the possibilities of the STB-3.

With the SDS2000X+ ?

[Martin72]

Where are the posts gone….

Anyway, by cleaning off the dust, I thought to myself it would be very nice to have a frontcover panel (like the one for the rigol 5000)  for my siglent  - Nothing found, only the expensive bag.
Is there something planned to offer such an accessory?

Nothing I'm aware of and yes the BAG-S2 is a little on the top side of acceptable pricing. 
However they do offer good protection from the good padding they have plus there's several internal pouches for all your probes and leads.
I keep all my demo units in these as they offer great protection when you're carting them out and about to customers or shows.

[Martin72]

For people who must carry it permanently around, this bag make sense, no question.
And the price...OK, it´s expensive but the mentioned cover for the rigol will cost 89 bucks - and it´s simply a piece of plastic...
Nevertheless, nearly every brand got these covers, perhaps sometime in the future siglent will offer this too.
Of course it´s not really important.
Edit:
After now 3 weeks of owning, I´m still happy with it, looking forward for things to come with the FW updates.
This could be a scope for our testdepartement.

[Martin72]

After several PMs arrived me, here is my verdict about rigol mso 5000 vs siglent sds2000x+.

Pros rigol 5000:

2-ch. AWG
HDMI Output
Four math traces at the same time
High waveform update range
Massive amount of trigger types
Massive amount of math types, especially filter functions the siglent doesn´t have
Up to 8GSa/s samplerate
Full usage of memory depth regardless of the timebase
Basic costs about appx 900 bucks.
Proper probes included

Cons:

Display seems a little bit dim and viewing angle is bad
Fan noise
Lagging of response what touch display concerns
Noisy frontend
Menu structure and knob arrangement design on the front Panel
Look and feel in general seems a little bit cheap
Only one firmware update so far, although it´s over a year on the market.

Siglent 2000X+ Pros:

Bigger, brighter, clearer display
Less lagging response what touch display concerns
Clearer menu structure
Clearer arrangement of the knobs on front panel
Suitable less noise fan
External trigger input
50 ohm input
8/10 bit Resolution
Eres function
2Mpt FFT
Bode Plot
Different colour math traces
More "adulter" look in General

Cons:

Less math and trigger functions
"Only" one channel AWG
Less waveform updates
No hdmi or vga output
Less samplerate
Soft power button

What the bugs in general concerns, I´m not nervous about it at the moment, this thing is brand new.

Martin, you missed the SDS2000X+ webserver that allows you to port the display onto any size monitor you like, grab screenshots directly at the PC, provide full remote control, and the SCPI panel and all without the need for additional software.

You need to have a play with it to fully appreciate its capabilities.

So what you are saying is that with the Rigol you simply plug the HDMI into a monitor, and with the Siglent you must buy a PC and configure some software in order to use an external display

No, it's different and let's examine a use case.
Why would we want to port the display when you already have a 10" touch display that's also keyboard and mouse compatible ?

To use the webserver all you need is a LAN connection and a PC on the same LAN with a browser open then all the features are available remotely including of course the live display which then can be used for a larger display or ported to a projector where it might be used in a presentation along with say a Powerpoint window.

All this can be done by just assigning an IP to the scope and pointing a browser to that IP. Same for the SCPI command panel.

Further, additional features are available in the webserver Instrument Control tab as shown here using the same setup I posted a few days back when giving SPI decoding tips to Martin but this time gathered using the webrowser's screenshot button which saves directly to the PC's browser download folder.
Sure this is from SDS5kX and the SDS2kX+ will be little if any different.

Saved screenshot via a browser:

[thinkfat]

OK, but the Rigol MSO5000 has a webserver, too, right? So it's not really an advantage for the Siglent to not have an HDMI output

[Martin72]

I don´t need a hdmi output, never need a video output on a scope.

Sure this is from SDS5kX and the SDS2kX+ will be little if any different.

I just try it out, it´s the same. The button "Instrument Control" is somekind of irritating as you couldn´t do much with it.
But the lan thing itself works.
