Siglent SDS2000X HD, 12bit, 2GSa/s high definition oscilloscope serie.

Additional points are better rotary encoders, better build quality in general and a dead silent fan.

That too !
Impressive when you first encounter it.

Just purchased a Siglent SDS2104X HD with the 200 MHz bandwidth promotion. My New Year's hope is that someone publishes a non-intrusive way to hack this scope

I also received my holiday purchase recently too!

Non-intrusive ?
You don´t have to open the scope for it, that´s for sure.

The HD is simply amazing for power electronics development, the traces out of it is straight up text-book worthy. I can understand why Martin wants to have the screenshots printed 

Bonus points if you can guess the topology and rough specs of the DUT.

Hi TopQuark,

Which currentprobe, same as last ?

Green trace is the ZLG ZCP30, yellow one is the old Instarance ICP5025.

I actually have a second ZLG ZCP30 ordered and on the way, maybe I'll finally review it proper when it arrives.

I recently upgraded from an SDS1104X-e to an SDS2104X HD.
Haven't put the 2104 HD to any serious use yet, but the FFT looks really nice.

Today I wanted to compare the waveforms on the 1104X-E with the 2104X HD.
The results are shocking to me (meaning how bad the 1104X-E is...), or am I doing something completely stupid.
Preconditions:
The signal generator is a cheap ebay  ADF4351 based board at 35 MHz.

The 1104X-E is un-un-locked  i.e. 100 MHz bandwidth. 100 mV/div, full bandwidth.
Connected to the signal generator and shares the signal via a T piece.

The 2104X HD is upgraded to 200 MHz. 100 mV/div, full bandwidth, 50 ohms input.
 
I have previously checked the -3dB limit of the1104X-E and it is about 120 MHz, so I am excluding use error there.

The amount of detail on the 2104 HD compared to the 1104X-E is shocking to me, or am I doing something seriously wrong?
Any feedback is very welcome.

Difference you see is because of reflections on a cable scopes literally get different signals..

Connect each scope to siggen alone, and terminate with 50 Ω (on SDS1104X-E you will need an external through terminator, 2000X HD has internal 50Ω inputs).
Enable dot mode on both scopes ..
Enable risetime measurements (with statistics) and then see the difference in risetime.
Take snapshot from scope on USB, on photos we can't see much...

Checking in with teh welcome committee.  Lol

Haven't done anything much with this yet but have to say build quality feels great and the interface seems really snappy.  First impressions are nice so far so thanks to everyone for the push in the right direction

That is what I have been saying even before they started selling them. 

It is some kind of flyback, is it not? A step up?

[Martin72]

Hi,

We got this as a poster in our lab:

http://www.downloads.freiraumwelle.de/TI-power_supply_topologies.pdf

Like the overview...

[TopQuark]

Yep, a dodgy DIY offline flyback for learning power electronics, 24V 5A output, 89% efficient

[Martin72]

Cool...

[Micke27]

@2N3055, thanks for the hint on enabling dot display.
The enclosed images are with direct connecton between signal generator and scope, both of them 50 ohm terminated.
My post was not about the bandwidth of the 1104X-E, it was more about the level of details resolved by the 2104X HD.

BTW, the risetime of the 1104X-E seems to correspond to my measured bandwidth, 118 MHz.
The rise time of the 2104X HD would correspond to about an incredible 400 MHx, nice for a 2104 upgraded to 200 MHz...!

Hello everyone,

I want to give myself a late Christmas present.
I was originally tempted to buy a Siglent SDS2000x+ but there is the 2000HD in the town.
I will work more and more with low power switching converters but I must confess that I still have very little experience and I have never been near an oscilloscope with a 12bit ADC.

The HD costs 2.5 times more so it's pretty significant and I'm not sure what this 12bit ADC will actually do for me in real life.
Has anyone ever done a comparison of the two oscilloscopes on sensitive measurements so that I can decide ?
Apart from the 12 bit ADC, is there any other discipline where HD is superior to X Plus ?

Thank you very much

Basically you will get less noise and more accurate measurements, people do not realise the low accuracy of the measurements in 8-bit scopes (at least for me), if you are going to use this scope for analog and over many years then it is a good investment.

Much better DC accuracy and MUCH larger offset ranges..
Much better DC accuracy and MUCH larger offset ranges..

It is so important that I wrote it twice.... 

You need 4.5 digit DMM to do better. And (much) larger offset ranges are great to measure on voltage rails.

Few more advanced triggers: Qualified, N-th edge, Delay, Setup/Hold
Tighter Clock specs..
Much better channel-channel isolation.

Wider environmental specs.

Yeah saw that on YT and he don't have both set the same. 
Like comparing Granny Smith with a sweet eating apple.

Which specific settings is killing HD's LA performance ?

Difference in speed is embarrassing to say the least.
