2.ADC
All the products did not use 4ADCs
are you sure? i see here only 4 ADCs chips (two on top and two on bottom PCB side)
brand seems to be Siglent, hardware rev. CA_M_111000 / SAT7.820.681O
So ?
and Siglent is using everywhere 4ADCs (like on the pictures of CA_M_111000 / SAT7.820.681O with no long memory).
It is probably like what you said in the first page. Done. Question answered.

I really don't mind, actually happy to see Siglent support here, but when you do this guys, do it properly.
Hello!
Today I was measuring things with my Siglent 1072CML scope (7 months old, latest firmware), and after accidentally pushing the Horizontal Timebase knob, and so entering Delayed Mode at a fairly slow timebase, the scope froze completely. Complete lockup. Even restarting didn't help, the logo shows, the buttons light up all right, and then the unused buttons' lights go off as they should, but the screen still shows the logo and nothing else. Buttons don't respond, I tried every button, including Default Setup of course.
Do you have some kind of a method for clearing the unit's memory? It seems I pushed the scope into some kind of an endless loop. It seems, the Delayed Timebase doesn't work with very slow timebases, but the scope remembers the timebase and mode I was in. How can I reset the scope without returning it to the warranty service? Thanks,
Andor
Another PS:
By using the LeCroy WaveAce programmer's manual, I figured a way to remote-control the scope. I reset the scope, then started an auto-calibration, then saved the status into memory slots 0 and 1, and this seemed to help. The commands:
*RST
*CAL?
*SAV 0
*SAV 1
This firmware is about half a year old. Please update it, we could use some extra functionality.
And if Siglent really reads this: an idea. A great firmware feature would be to offer intensity-graded display, as on more expensive scopes. Those scopes perform >50000 waveforms per second. This scope only <=2000 wf/s. But if I had an option to see the actually captured waveform, while the DSP/FPGA calculates a statistical intensity-graded waveform based on the last 50000 waveforms... It would be great.
You wouldn't even need much of a memory for that. You could simply add a value saying "okay, I want statistics based on X waveforms". Then, each new captured waveform would count as 1/X in the statistical memory. Would it be possible to implement such a thing? Or at least, as a function of the EasyScopeX software? Thanks,
Andor
I believe Extech is on here. Not sure about Fluke, Rigol, Tek, etc...
I recently started having a problem with the auto button of my SDS1102CML. When making measurements with the x10 setting of the probe it almost always expands the signal to fit the entire screen. But with the x1 setting of the probe most of the time it compresses the view (increases the time base and reduces the amplitude) so that you do not see any detail and have to adjust both the time base and the amplitude. Is there any particular reason for that?
P.S. This occurs mainly when visualizing the reference square wave of the scope. With an external signal there is no such problem.

this problem has been sloved, you can upgrade to the latest version from the http://www.siglent.com/cn/server/download.aspx?nodecode=105004002006

(yes it works as long as keep DC coupling selected.)
Note. It looks like it is related to frequency. If I use external generator for 1kHz and 3V square also B ok. But only if frequency is enough different as scope own 1kHz. Scope own 1kHz is derived from scope clock. If I use external 1kHz what is enough close scope own 1kHz result is same (fail) as with scope own 1kHz probe comp signal. For more fun, result is same if I use external signal but adjusted enough close to what scope think is very close 10kHz and same with very close 100kHz.
