Siglent SDS3000X HD and upgraded SDS1000X HD

[Performa01]

I use only the web interface. I have never used flash with SDS3000X HD.

Yes, older FW always used the same simple filename. But current FW makes that distinction and you can easily try this by repeating my experiment, i.e. saving a screenshot to a flash drive.

The Filename used for saving to flash is configurable by the way...

Hello,

the behavior when generating the file names in the web interface has changed without me having made a firmware change. I suspect that a function in the browser has been changed. I will check this by using a different browser.
My suspicion was correct. Firefox still generates names like ScreenImg(2).png.

So it was the Edge browser.

Let me remind everybody that if you create a map to a folder on your PC (using SMB Client), then you can directly save to PC.
Also, since scope remembers last filesystem used, once you save to PC firstly, from that point on it will keep saving there.
So you press [Save]button on scope, and screenshot ends up on a PC. Or data, whatever is set.

Pay attention that 3000xHD saves data to PC at almost 100MBytes/sec... It is very fast.

My workflow is easy. Making a screenshot in the web interface, open it in the download folder with Irfanview (my standard image viewer), invert it for printing or combine it with other snapshots and store it in a dedicated folder with an dedicated name for later use as JPG.

And that is what I also do..

But sometimes, as you work on something, you can simply document things as you go, directly from the scope. Or when testing a small batch or repeating measurement while making changes on circuit. There are many scenarios where it is simply more ergonomic not to jump between PC and what you work on.

We are fortunate that we can choose way that suits us best.

GbE being considered "fast" on a $3000 device is so disappointing. The FPGAs can support 10g+ if only the manufacturers exposed a sfp+ cage

And it can support anti aircraft gun too if you add that too...

Better check what kind of speed you get from competition...

In practice, there is a difference between possible and sensible.

Hello,

I would like it, if there was a USB3 streaming mode.

[egonotto]

Hello,

I had a look at what you can achieve with average.

Best regards

PS: With the MHO3 you can only set 256 averages and only get 1.7 uV (AC RMS) and 15 uV (pp) with comparable settings.

[Bad_Driver]

I did the same with my SDS2000X HD fyi, see attached. Seems to be a little bit noisier.

Egonotto, why have you limited the sample rate to 100 MSa/s?

[egonotto]

Hello,

there are a few threads here that deal with accurate and extreme LCR measurements. This has inspired me to see what is possible with an Analog Discovery. It's quite good, if you disregard the accuracy. However, the Analog Discovery only has 500 mV/div, so I wanted to know what could be achieved with an SDS3000X HD. The selected settings seemed to me to be a good fit.

Sounds interesting.
Which software can be seen in the picture?
And the data for this came from the 3000X HD?

That is Waveforms software for Analog Discovery.
You can try it, it is interesting. Works with a sound card for basic testing..

Hello,

no, the picture is from the Analog Discovery 3. but if you consider how much more sensitive the SDS3000X HD is, for example, you can imagine what good results you could achieve with it and a function generator. Not only is it more sensitive, but you can also adjust the V/div in the program (that still needs to be written).
If you consider that a coil of 1 uH at 100 Hz has about 0.628 mOhm, but at 10 MHz it already has 62.8 kOhm.
The Analog Discovery could no longer measure anything at 100 Hz, but the SDS3000X HD could still measure the 12.6 uV at 20 mA.

OK, I figured since it was posted here in this thread, there must be some reference to it.

The user mawyatt had already done something similar, albeit not with an HD scope.

I still think the request to Siglent contained therein is worth supporting...

[egonotto]

Hello,

@Martin72: In Dave's video about the HD3 (37:26), he shows a signal of 15 uV and 50 MHz in the FFT view. It can be seen there with about 15 dB above the noise.
He then shows the same signal in the MXO4, which is barely visible there.
You have an RF generator that can generate a 15 uV 50 MHz signal. Can you please try whether the signal can be made clearly visible in the SDS3000X HD in the FFT view?

Best regards

[Martin72]

A quick shot without having seen the video, I'll watch it later or tomorrow.
SSG3032X with 15µV/50Mhz, scope 50Ohm, AC.

[egonotto]

Hello,

Thank you, that looks very good.

I hope that I have understood Dave correctly with 15 uV. My English is very bad. 

Best regards
egonotto

[Martin72]

I asked in the thread, but at the moment I think that the 15µV will be attenuated by another 12dB - and you won't see that anymore.
I played with the level again earlier, 5µV can still be clearly recognized, 1µV no longer.

[egonotto]

Hello,

thanks, yes I looked at it again and it seems that there is only about 3.7 uV.
The noisefloor of the HD3 should be about 5-8 dB better at this settingv than our SDS3000X HD.
However, the HD3 no longer looks so good at 1 V/div. So twice better is not even better.

Best regards
egonotto

[Martin72]

If I get the right settings, I'll try again.

[hpw]

yes I looked at it again and it seems that there is only about 3.7 uV.

as using 12 dB attenuation of 15uV... as Dave speaking

IMHO, as reading the DD3 user manual, the 64k FFT & detectors may unique on the HD3 

[2N3055]

In that Dave video signal is 3.7µV RMS (cca -95 dBm).
There are some parameters on the screen: bin width is 24.4kHz, 3.2 GS/s, 128k samples. Window and averaging is not specified .

With SDS3000xHD set to similar parameters: 128Kpoints, 25.02kHz Bin spacing, Von Hann, 4 averages.
Speed of FFT updates on the screen is similar to Keysight.

I think it can be seen just fine.

Yes, misleading by Dave in that video by not putting the scopes in comparable settings/configuration.
