It'd be nice if there were options like on the Rigol DP832 for brightness and screensaver. For now I have the display disconnected. It's powering voltage references and the logging pi. Wasting energy on the full brightness display seems pointless as it never needs to be touched. I needed my channels from the Rigol back though(it's in a better position) On the Rigol I only use the screensaver so that it turns off the display which I keep brightness down on as well.

Ok, so I guess you have a X or X-E model PSU.
Thanks, I'll send through a request that more display management options be added into one of the front panel button menus.
It seems logical it be added into the Timer button as a Display submenu and use the Left/Right buttons for navigation and the encoder for value changes.
Care to think through and offer a display management menu structure ?
Sure, when I have some time I'll reconnect the display and see what would work best, in my opinion.
Hello everyone!
Sorry for my poor English, I am not a native speaker, but will try to explain the problem clearly.
I have the Siglent SDS1102CML+ oscilloscope. The issue is that the oscilloscope does not boot. It is frozen after turning on and shows only "Siglent" logotype. The buttons light up, but nothing happens. The version of firmware is 6.01.01.21R2 (Release Date 09.25.19 ). Did anybody deal with this issue? Are there any ways to recovery the oscilloscope? It looks like the firmware was corrupted. I see that on main board the sd-card slot exists. Is it possible to use it to flash firmware?
Thanks!

Welcome to the forum.
Press Math repeatedly and rapidly when booting.
Try multiple times if this fails at first.
I tried to do it multiple time, but it gives no result
I read that this can work on Siglent SDS1102CML, but my oscilloscope is Siglent SDS1102CML+

It is the standard boot freeze recovery method for all CML, + or otherwise.
The Math button presses must be fast and many.
Please try again and report back.
If zero success I do have a CML+ USB recovery package of 12 MB but I will need your email address so please PM me with it.
tautech, I thank you a lot! The recovery pack helped me to repair oscilloscope. It works now!!) I am really glad that I found this forum!
May I ask for which Siglent device types "this type of recovery" is possible ?
SDM3055 and SDG1062X too ?
Thank you.
Good to know.
I would be interested in how the process of this type of recovery is handled ?

Depends on the product and its firmware status/version but initial attempts are via USB files auto uploaded at boot to replace/repair the OS
if the currently installed firmware supports it.
Older non updated devices (with old firmware) may require access to the internal SD card slot to use the same file fix/replace process however a different recovery package (SD or USB) is required for each process.
These recovery files are available only on request and are NOT to be shared or made available to the general public.
Hi,
I have this unit that was returned to the factory for startup failures, now no more start issues, but the voltage measurements are wrong, shows 70% of actual voltage. DC and AC are same, I tried with different probes, I made several calibrations but it's still the same.
SDS1104x-e, upgrade to 1204 on factory when repair startup failure.
Software version 8.1.6.26. with the last firmware 6.1.33 the measurement voltage is wrong, same value 70%
FPGA version 2018-07-26
Hadware version 01-04
Thanks in advance for yours comments.
Reset to factory defaults and redo measurements please. Pay attention that probe and channel attenuations match.
Hi,
I reset to default, the probe and channel attenuation are same, the measurements are wrong still.
I will be attentive for any indications
"I will be attentive for any indications"Well here's a couple of random ideas.
Edge trigger's not the best for capturing DC levels, use AUTO or AC LINE to keep the DC trace updating.
Eliminate the probes, it's safe to hold a bit of wire between the scope's 3V 1kHz and the center of the BNC, - don't force it in, to see if the 1kHz is 3Vpp.

Hi, thanks for you help, with the wire the result is the same, wrong voltage measuerement, I use a fluke 192 to check the Siglent Cal signal, the measuremet is exactly 3Vpp.
Check the other channels, I can't think of any sensible reason why it's showing amplitudes only 68% of what they should be.
68 - 70%... Not far off RMS?

Yep, there's something wrong with that screenshot as the probe Cal signal is 3V p-p.
Contact your dealer and send him that screenshot and ask for another scope or this one to be repaired with possibly a new mainboard under warranty.
But first, are all other channels the same and measure low ?

All channels are same. it's a strange fault

Tech support have been alerted to this.

Yes, we think there is a calibration problem.
When Autocal is entered there is a warning that all leads must be removed.
Can you confirm Autocal was run with all probes and leads removed ?

Yes all probes and leads are removed as indicate the instructions, I run the Autocal several times with the same result, wrong voltage measurments.

OK, thanks. Expect a PM with contact details and more info that Siglent need.
