REVIEW - Rigol MSO5000. Tests, bugs, questions
vicki20july:
Hi Martin
Thank you very much for the post and your experience. It is very informative.
What about the 200 Mhz probes if i upgrade the Siglent to 500 MHz. Would they still hold or I would need to buy new more expensive ones above 200 Mhz measurements. I believe the MSO5074 comes with 350 MHz probes. Does this make any meaningful realistic difference in performance, comparison wise.
Also what is your opinion on the 8Ga/s vs. 2Ga/s. Is this really a limitation for Siglent when put to real world use or compared against MSO5000.
Thank you

Hi,
Your questions would fit better in the thread I´ve posted before...
Nevertheless:
All depends on what your needs are..
At work we got some elder lecroy scopes which are having max. 1GSa/s and 500Mhz bandwith and we aren´t having any problems with it at all.
Because our needings won´t reach the "spheres" where this could make a difference.
Same by me in private.
Same what the probes concerns.

AFAIK all 4 channels in MSO5000 are processed by one ASIC which sampling rate gets divided down by the # of channels active.
SDS2000X Plus has two, yes two 2GSa/s ADC's so if an input is assigned to each ADC the max sampling rate in unaffected.
Therefore with 4ch active sampling rate is 1GSa/s, sufficient to meet Nyquist at 350 MHz but not at 500 MHz where the SW dictates it to be a 500 MHz 2ch DSO or if 4ch must be used restricts capability to 350 MHz.
On each active channel tab this info is displayed for the user to be fully informed of how the scopes is configured.

ok thank you both of you for the info. Now you guys got me thinking about the Siglent again. Will make my decision in next couple of days. Can anyone please answer my point no. 3 above. Repeated here.
"Is there a list of some common / basic tests that I can do to verify the proper functionality of the oscilloscope upon receiving. If possible, please highlight some basic / quick tests that I can do to verify this. For peace of mind, I would like to ensure that the Oscilloscope I received is functioning as intended and does not have any hardware related issues. Any help is greatly appreciated."
Thank you All

But if you can spend appx 400 bucks more there is, in my opinion, no alternative to the sds2k+.

It's not $400 more at the moment, but... that about sums it up. You could stop reading there.

It never has more than half of the Rigol.
You can use the extra sample rate on the Rigol reduce noise by oversampling. This is a new feature added in a firmware update (it happens!) so it makes all older threads that discuss noise less valid.
It won't ever be as good as the Siglent, noise-wise, but how much the noise affects you depends on what type of signals you''re looking at. If the signal can be made as big as the screen then it makes no real difference. It's only a problem when the signal is tiny compared to the screen.
TLDR; If you mostly work on digital signals then don't worry.
People will go on and on about "power supply ripple" but some people might say that if ripple is too small to see on an MSO5000 then it's not really worth worrying about.
The Siglent is obviously better, but ... it's 70% more money right now. If that's a lot of money to you then take a moment to think what else you could spend that money on.

Power it on.
Run self-cal, see if it finishes.
Connect all 4 probes to the test signal, see if it's there.
Switch between DC and AC coupling on each channel.
Turn the vertical up and down and listen for relays clicking (I think they both have relays, right? Correct me if I'm wrong)
Press all the buttons, twist all the knobs.
