I've asked the status of the issue (figured my direct contacts should work quicker than the distributor + tech support chain) and learned the following:
Siglent have identified the problem. The new version isn't compatible with all the previous ones. There will be a new package release soon that will fix that.

Thanks a lot Performa01, that was very kind of you   :-+

I'll wait for the update then. Thanks again.

Well, I would guess if you update to the 20R1 firmware prior to attempting the update to 25R1 then everything should work fine. It's only some older firmware versions where there's a compatibility issue. At least I had absolutely no troubles updating from 7.6.1.20R1 to 7.6.1.25R1 and I think the same is true for all the others who made this update step. The only other issues have been with the OS update when using incompatible flash drives.

Everyone who had compatibility issues with the latest firmware update, please find the corrected package for V7.6.1.25R2 here:

https://www.siglentamerica.com/download/6422/

EDIT: Siglent seems to have done their homework. There's a lot more fixes than just the broken remote control:
  • Fixed the bug: Once the acquisition is stopped, the scope often can't find search events in other channels.
  • Fixed the bug: In certain situations, the scope freezes when the Auto Setup button is pressed.
  • Fixed the bug: The Pass/Fail mask is not correct at edge of screen left and right.
  • Attenuation and invert indicator were added into the channel tab.
  • Any arbitrary probe factor from 1e-6 to 1e6 can be set by universal knob.
  • Got rid of suffix 'A' that stands for 'Acknowledge' from I2C decode.
  • Fixed the bug: The dedicated window for long I2C data sometime lose data at right edge.
  • Fixed the bug: The decoder sometimes does not show any info.
  • Fixed the bug: After updating to the last firmware and OS version, the remote panel/control interface can no longer be connected.

'I' for Invert.
Updated screenshot.



OK Siglent, good stuff.  :-+
Now please add some of this to SDS1202X-E, er no, actually all SDS****X models.

Custom probe, now adjustable to 6 decimal places and settable to even more than that. Not that more than 3 digits would make much sense, but better too many than too few ;)

In a few months of such an improvement's speed people will finally get their "ideal oscope", it seems :)

You are right, those 0.123456789x is something people would not appreciate too much, better to stay with 3 digits and an exponent, say +12..-12 (tera..pico). Best in "Engineering" notation/format..

We certainly get the engineering notation if the factor calls for that:

Examples:
Code: [Select]
1.23 x
123 x
1.23E-3 x
12.3E12 x
-235 x
-2.35E6 x
-23.5E-9 x
-235E-12 x
..
These coefficients must not be related to the "probe attenuation or gain" but generally to a "measurement". For example you may watch an waveform at the -2.5V/100pA output of your DIY pico-ampermeter, with stock 10x probe. So you will dial "-2.50E-9 x" in.

Can't wait having mine... it's in transit, should have it in a couple of days, with the LA option  :)
And funny enough, my old Hameg 205-3 just "died" 2 days ago, leaving me with a crap DS-203 as my "main" scope (better than nothing). Already repaired it a couple of times but this time it's the CRT and I don't have a high voltage probe. So far so best.

Siglent does seem to do a good job at fixing their software, that's good sign.

Just installed the latest update and I can confirm it solves the issues with the remote panel not being accessible.
Now everything works as expected!

I have to say that I'm really pleased with Siglent response and attitude  :-+

Thanks to Performa01 and simone.pignatti for your help  ^-^

Using the 4ch 4 different probes setup from a few posts back I shot a very basic vid showing remote display responsiveness for possible any big screen or projector presentation use/needs.
SDS1104X-E webserver via WiFi to laptop which in turn is connected to a VGA 18" monitor. Took only a minute or two to setup.
Done from my phone so nothing flash, just a quick demo.

The latest 25R2 firmware update fixed the problem with I2C decoder and a strange suffixes. Now it can display long strings (it looks a bit bizarre though due to the strange padding but none of data is truncated now).









It is still  not possible to display the long data correctly at the string located at the bottom of the screen, you will never see the end of the decoded data of the packet longer than 30 bytes simply because Siglent does not allow to scroll the bottom string to the left - the first decoded byte must be always visible (but why?) and therefore most they can show is 30 hexadecimal bytes.  Not  a big deal for me. May be one day they will fix it simply to be not just  "really good" but "almost perfect"  8)

I've completed the update without any problem, everything works and the webserver is very nice now

Thank you for your support

It seems that Siglent fixed that I2C display issue quite quickly. That's enthusiatic.

Thanks for that!  I just happen to have some 27" monitors on my PCs, a perfect size for old people.

That scope is looking better and better.  One of these days I'll have to buy the SDS1204X-E.

Thank you.
Yes there's nothing like a small video to show the real responsiveness.
That was just really to demonstrate how they can easily be used for presentation purposes, something that you'd ordinarily need to spend a lot more $ to achieve with a DSO.
You've probably seen screenshots webserver remote UI and that's quite excellent too and full control can be done with a mouse.......maybe another simple video coming........but with a small digital camera instead of shaky damn phone.

When I communicated with rf-loop shortly before these were released, the phrase 'hardcore' he used alerted me to how good these really could be, even though I'd beta tested one and had some idea this was the case myself.
His words based on his vast experience are proving correct.

They're certainly very well featured for the money and very few won't be surprised of how capable they are. For the 'first DSO' buyer these are truly a scope you can grow into by adding further functionality options when you need them.
It's certainly the best value for money we've seen from Siglent as yet.

Yeah I know.......sales blurb and all that, but look hard at other offerings and those that can really see will see what owners do too.
Also thanks to those that have given the valuable feedback for Siglent to improve these DSO's to what they have become.  :clap:  :)

Siglent USA have done a short video on the webserver.
Some explanation on the improvements, usage and further improvements to come.

me if this is a known bug?

Sorry for the separate thread, do I need to ask things like that in this thread?

Looking into the SDS1000X-E fw, one can see that the 250Mhz and 300Mhz is a possibility (in sw terms, at least).

So that would mean a SDS1254X-E or SDS1304X-E only would lack a proper "logo".   :popcorn:

And that would match what I've read in this thread that Siglent has 300Mhz probes in the inventory.

If anyone wants to test these bandwidths...

considering the fact its will go down to 500MSPS when both channels on the same AFE are active, 200MHz is about the maximum. You could go higher when only a single channel is active (at 1GSPS), but then there's a need to add this LPF back to avoid aliasing with more channel active. Would be interesting to see if its implemented this way   ;D

Looking into the SDS1000X-E fw, one can see that the 250Mhz and 300Mhz is a possibility (in sw terms, at least).

Here is screenshot of 100 MHz square wave with 1 ns rise time. I got it with my 100 MHz SDS1102X:


The Rise time is measured as 1.70 ns, it corresponds to the bandwidth = 0.35 / 1.7 ns = 205.8 MHz   :popcorn:

And here is even more - 290 MHz square wave with 1 ns rise time:


The Rise time is measured as 1.02 ns. The bandwidth = 0.35 / 1.02 = 343.1 MHz...  :bullshit:

Very interesting. As far as I know the recent versions of firmware don't provide 50 om Impedance option for SDS1XXX X-E series (1102/1202 - 1104/1204), this menu item has been removed long time ago. Are you running some sort of a very old firmware?

BW is dictated by the -3dB point, nothing else !
Significant signal attenuation is evident once you go past the rated frequency

The SDS1102X that radiolistener has is a different series to X-E and does have 50 ohm inputs.
