By the way I do have problems with some intermittent contact loss on three logical channels, see attached photos. The connection to the scope seems to be the area of the failure as this effect can be provoked by slightly wiggling the connector on Scope side. Does anyone else have seen comparable issues?Just checked a unit I have here with very few if any Logic probe cycles and yes some intermittency in its connection here too however on just one channel.
So I pressed and held both probe release catches then pulled and pushed it a few times to clear any possible tarnishing from the pads and contacts which seems to have totally fixed it.
So it seems just a few removal/insertion cycles will improve intermittent connections.I did the cycling trick as well. But the effect remains. I hope it is a contact surface problem anyhow on PCB side and NOT a problem on Scope side (Connector, Soldering, PCB)...Understood but let's look at the PCiE socket which I think is through hole and millions of them get soldered onto PC PCB's without problems.
Someone mentioned a while back they do have a mating cycle life however without looking it up I don't know what it is. Maybe yours just needs a few more insertion/removal cycles ?
Time to get my magnifying glass out .......true, so probably on probe side. It is interesting that it is related to channel 8, 9 and 10 which are located at the edge of the PCB connector (thanks to info from Vestom). Hmmm
I contacted my supplier for further treatment, let's see.Update.
A close inspection of the MSO probe plug didn't identify any obvious issues however cleaning of the PCiE plug PCB pads with a cotton bud and IPA has solved all intermittent MSO probe connection problems.
Note, one side has just enough clearance for an ordinary cotton bud while the other side requires a thinner bud or one bashed/squeezed thin or stripped down some.
I'll be checking new stock MSO probes for any repeat of this issue and advising Siglent if there is.
Hi guys,
At this time i don't need high R&D capabilities of my Lecroy wavepro oscilloscopes, and i am looking for some smaller oscilloscope.
I have some questions:
1. How good this siglent are in terms of DC offset and saturation? In Lecroy scopes you can offset you signal and "zoom in" up to several times needed piece of you signal without distortion. I mean this https://youtu.be/n_dXvpEV18g?t=155
2. Can someone provide screenshots of sin 200Mhz and 400Mhz with linear interpolation (without sinx/x interpolation) with 2Gs/s and 1Gs/s SR?
3. Can someone provide screenshots of fast rise meander with linear interpolation (without sinx/x interpolation) with 2Gs/s and 1Gs/s SR?
Thanks!

Can anyone help me?
Thanks
hi Howardlong, i really appreciate for your help!!!

As can be clearly seen sinx/x interpolation is used
https://www.eevblog.com/forum/testgear/siglent-sds2000x-plus-coming/?action=dlattach;attach=1069288;image
at what V/div setting there are no visible distortions of a signal? 50mV/div or more?
Best regards,
The noisy front end I don't believe is retrievable.
I was not interested in china scopes
hi Howardlong, no more questions, again thanks for you help.
I was not interested in china scopes, but Siglent SDS2000X Plus seems not bad "Lecroy copy"
No, video from rigol was only for illustration what i mean and what Lecroy wavepro oscilloscopes can do.

The effect of wasting peoples time is that they're less likely to help others in the future. If you didn't care then why did you ask?
No, video from rigol was only for illustration what i mean and what Lecroy wavepro oscilloscopes can do without a problem. But can Siglent do that is an open question.
Can Lecroys do that? Front end offset and saturation are two different things. What is the Lecroy's front end saturation recovery speed?
Can Lecroys do that? Front end offset and saturation are two different things. What is the Lecroy's front end saturation recovery speed?Hi Howardlong, sorry, its my poor english, I misled you . I mean huge frontend DC offset when it linearity is acceptable. But mean saturation in terms of screen, when part of signal is "out of screen".
Pls accept my apologies

A few months ago, I was on the decision taking the 1032X or 2042X, because I wanted an external AWG additional to the inbuilt version of the sds2k+
I took the 1032X, turned it to 1062X and never regret it.QuoteI couldn't resist more
You won´t regret it, the sds2k+ musn´t fear any seriously opponents until say 3000...4000bucks, although it did´t got the super-duper 8GSa/s the rigols got.
We must not exaggerate
Martin72, weren't you the one who bought a rigid case for transporting the scope? Do you have a reference?
