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

[kripton2035]

I was lucky to benefit of the "end of year" siglent promotion, you get all the decoders for free, and one bandwidth upgrade for free with the scope.
it was a far better promotion than the PA licence...

If you have scope connected over LAN you can mount any folder accessible through LAN and save directly there.

Now this is more 2023 !!!! tried it, works great, thanks ! The Siglent spectrum analyser doesn't have this feature, man this sucks, it was done by a different department !

- Is there a way of retrieving files out of it? i mean it has the webserver, but if i want to save a picture with a white background, i would have to save it on the internal memory and copy it via USB sitck? if this is the case this is kinda so 2001.

PA is a fine thing on paper, I have thought problems to build "antennas" in the circuit, so that I can measure current with a current clamp at all.

Good point, I have absolutely no experience in this kind of measurements and have no idea whether this measurement scenario shown in the Siglent brochure is realistic. They are taking the current measurements on the external wiring of the power supply. Well, anyway I think at least its a good idea to own a differential probe for measurements on equipment powered by switched power supplies.

The full suite of PA measurements require passive, differential and current probes.
Each measurement type requires specified connections clearly outlined in the Connection Guide in the PA menus.

Some of which are rather unrealistic, e.g. all where a current clamp is drawn in the signal paths (G,D,S) of the switching FET.

I really would like to get one of these hard shell cases which Siglent NA is selling. I wonder why its not available in Europe.

I had bought that for my 2104Xplus at the time:

Fits also for the HD.

I am trying to figure out what current probes to get without becoming broke :

First option it's better for lower currents with a lower bandwidth:

https://www.farnell.com/datasheets/1872317.pdf

But for me it's not clear the minimum current it can measure is it 2 mA? if so that's not bad

Second option :

What do you guys think ?

The 2 are not related.
Needs dictate the ultimate decision, they are ?

[amar87]

needs would be for both....

[MathWizard]

So they didn't make 2CH versions of the sds200x HD's ?

[2N3055]

Nope.

[tautech]

Type of use, not spec.

Need both AC and DC capability ?

SMPS use or something else ?

[Martin72]

What do you guys think ?

I had a pico clone from Owon and the micsig in the 2.5Mhz version.
The first was the definition of crap and it should be forbidden to offer it.
The micsig was a nice surprise in terms of building quality, but not suitable for currents lower than 50mA - And it´s "huge" (like the owon).
If you want to use the PA option for detailed examining of SMPS you should look for probes with low noise, high bandwith and small dimensions.
Siglent offers two probes in this direction, also the new micsig probe could be interesting - But both have one thing in common, theyé not cheap..
In my case I´ve ended up by buying a good old tektronix system (TM502/AM502A/A6302).
Two cons : Max. current (30A) and space on the desk.

Is that really what you are looking for? Just one ADC with 1GSa/s when using both channels?

Which of course has only sufficient sampling for 350 MHz for a 500 MHz product range.
Designers as you have recognized are smarter than that.

So the topic of slow digital acquisition, compared the the plus model, was still not answered? Will that be revisited? I do not see any firmware updates since last September. Maybe I will stick to a plus.

[Martin72]

I do not see any firmware updates since last September.

This was also the first and until today the last update.
The scope is next month for a year on the market and to date only one update - very unusual for siglent relations.
But my trust in the brand is strong, they will have their reasons, that makes me wait patiently.
In addition, and this must be said, the existing bugs are rather annoying nature and not decisively hindering.
Nevertheless, it's time...

[kripton2035]

pretty sure we will have a 2000HD update when the 1000HD is out for sale.

[Martin72]

Yepp, +1

I am trying to figure out what current probes to get without becoming broke :

Get a Tek P6042 for 300 USD. Both DC and AC to 50 MHz (yup!) It's still a stunning piece of equipment yet a drift ba**ard. Have it warm up for one hour at least. I use it daily with the SDS2104X HD. You won't find anything with those performances for the price.

I replaced the zeroing poti (it's not auto-zeroing) with a multi turn one and works like a charm.

Pay attention because the hall sensor epoxy glue is fragile like an egg. One drop and it's gone (known weakness) and also pay attention to the cable because it's prone to internal open circuits. The cable is custom and very hard to replace due to soldering.

The manual is a masterpiece and the calibration procedure is clearly detailed.

You won't regret it and you will save plenty of money.

[EE4all]

How usable is the HD above 350 MHz? Where is the 3dB cutoff? 6dB? Near 500MHz? I didn't see any review trying to use it at the limits.

[Martin72]

Where is the 3dB cutoff?

Interesting questiion..

Normally, the model specification of the bandwidth describes the value where the -3dB point is - at least.
Most of the time, the bandwidth is slightly(sometimes more) higher than the model specification, regardless of brand/model.
So you can assume that the 2354 model actually has 350Mhz as a -3dB point, rather higher.

[EE4all]

True, but many also perform quite ok well beyond their specification, with degraded levels, and can serve in a pinch. It got me curious about this one.

[tautech]

With X Plus models -3dB is often well above stated BW with 500 MHz models near 600 MHz.
Only SDS1204X HD here currently and it's 280 MHz but not pushed to see how far it can go....a job for later today.

[Martin72]

Afaik you can determine the bandwith without having a signal source going so far.
No, not the bodnar pulser (risetime), it was something else...with FFT...Can´t remember...
