I found a mismatch between channels in my unit.
How are the versions of Siglent manuals numbered? For example, I have oscilloscope manuals versions UM0101X-E02A, UM0201X-E01D and UM0101E-E03C. How can I know which one is the latest?
You might get a smaller mismatch if you switch to 500 mV/div, because the LSB gets smaller - is that true?
Also, is the bandwidth limited to 20 MHz on both channels? A BW limiting mismatch can contribute to min/max mismatches.
FEATURE REQUEST
Did you notice the Siglent logo on the screen of SDS1000X-E? To me it looks ugly and cheap. I thought it was the same on all Siglent scopes, but the screenshots SDS5034X in this topic show that there is another much better looking version.
I pasted the logo from SDS5034X to a screenshot from SDS1000X-E. Just compare the two versions and see the difference.
Question to Siglent: would it be possible to change the logo on the SDS1000X-E screen? I know that we are talking about a piece of measurement equipment but if it can look better why not to do it? Aesthetics is also important. This small detail will make the screenshots look more professional and not cheap.
Lowering the supply voltage is of course a possibility, but the cooling must also be sufficient.
An idea for Siglent: make the voltage to the fan dependent on the cabinet temperature. That would make a big difference!
What was the original fan type / manufacturer? I am going to use Sunon MF60251V2-1000U-A99.
My SN# range is: SDSMMDBC2R****

Today I started changing the fan. My guess was confirmed. The fan is important but also the shape of the inlet (shape of the cutouts in the housing). Fans with a large diameter of the blade mounting part perform better in this model. So the fan blades should be short. Then the shape of the inlet less affects the noise.
My fan (MF60251V2-1000U-A99) is quiet but when placed on the housing it becomes loud. I solved this by reducing the voltage to 7.5V (I added a 100R resistor). I checked how strongly the air was blown out. I did it by hand so it is inaccurate. However, in my attempts it came out that the Sunon MF60251V2-1000U-A99 at 7.5V blows just as much as the original at 12V.
In my model SDS1104X-E there is also a PAAD16025SL fan and the serial number starts with SDSMMDBC2Rxxxx
Apart from all:
We got a siglent SDS1104X-E at work, our colleague from R&D use it in his office and the noise level seems to me (and him) nearly quiet - Maybe you got a defective one ? (what the fan concerns)

didn't know it could be a serious tool 😁

This tool was spotted twice in this video according to comments. People choose Siglent.
