Siglent SDS800X HD Review & Demonstration Thread

--- Quote from: Performa01 on May 06, 2024, 12:50:17 pm ---.... why do I even try to compete with an upper midrange instrument from LeCroy by using a low-end entry-level device like the SDS800X HD? (Answer: because this is a thread about the SDS800X HD)

I show the LeCroy to better explain what I am asking to see. Some of these low cost scopes are very impressive.

With all that said, I pull out a worthy contender for a change:
...
SDS7404A
...
In the above screenshot, a 999999.5 Hz sine was combined with a 1.0000000 MHz sine, hence the difference between the two signals is 0.5 Hz or 0.5 ppm. ...

The 7404 is very tempting except it's not good enough to replace my old WaveMaster and it's way overkill for what I am looking for. After looking at what they offer, I am starting to lean toward the SDS2354X HD (?). It appears to offer some improvements, but I also give up in other areas. I would like to see where someone had ran this thing using the Ethernet interface. I've not found anyone showing any custom applications for it. Have you written custom software to interface with any of your Siglent products? If so, I would be interested in hearing how it went.

Today, at work...
Lecroy Waverunner 9054(8bit), HDO6034A(12bit).
FFT with 100khz span, source Siglent SDG1062X, 50Mhz, 0dBm, 50Ohm.
Maybe we should have the last pages separated and moved to a new thread, title suggestion "FFT comparison and settings".

That's fine. Personally I was really just asking how the low cost Siglent dealt with these cases I have brought up.
Martin72:
This is also a very exciting topic that "deserves" its own thread.
Let's see if a moderator reacts, then he can also take this post with him.
Again 50Mhz 0dBm, Siglent 824X HD, 50Ohm termination.
Span 10khz, so far so clear.
I have combined 2 tracks, the current one is at a vertical setting of 110mV/div (C1), the REF B track(purple) is at 100mV/div.(C1)

Sorry Martin,
just a last one. ::)
Similar to LeCroys: 50 MHz, 0dBm,20dB/div, 100kHz span, 83Hz RBW , FlatTop W.
200MHz BW limit on (HDO6034 is not 1GHz)
I think it looks very good. Noise floor is good 10 dB better.
