SIGLENT SDS1102CML - First Impressions

50Hz, so its picking the mains frequency somehow.
Do you know how can I prevent this?
When I moved it to a different room it stopped.

This is normal, the probe and oscilloscope constitute antenna system, the signal waveform that on the screen of the ambient radiation ( such as power radiation etc. )

Hello to all!
@hgg: Really nice review and pictures!
--- Quote from: hgg ---Some measurements.
- Power Consumption : 18.7 Watts
- Temperature : from 23 degrees Celcius ambient to 34 degrees after one hour of use.
The hottest part is the right side.
- Time to boot : 9 seconds.
- Time to Auto trigget its own signal : 5 seconds. It can become much slower with different signals.
- You can hear a relay clicking when you change from 200mV to 500mV and from 50ns to 100ns
- Software Version : 5.01.02.13
- Hardware Version : 11-62-3.3
- Sound Noise : Its a very quiet oscilloscope! My house is very quite.

I have a little confusing question, NOT related to SDS1102CML but to SDS1072CML (Siglent)! It is HW version "issue".
I will get Siglent SDS1072CML for about a month :-+, it is already bought from amazon.de (299€) by my cousin living in Germany. Scope came very fast, everything (visual) seems fine. I asked before the seller (Futu-Tech) what are exact hardware and firmware versions for this scope: seller answered me next day: HW version: 11-66-3.3, and FW: 5.01.02.13 (the latest if I'm not wrong).
Since my cousin doesn't know virtually anything about that kind of equipment, I asked him (remote assistance by the phone hehe) to turn scope on and to tell me HW and FW numbers from utility\system status!
The Firmware ver. is : 5.01.02.13 (seems ok), BUT
the Hardware version is: 11-62-3.3 !? -just like on your 1102 (100MHZ) scope, not 11-66-3.3 as it should be?
I don't know anything else, besides very very quiet fan!
What do you thing what is what here?
As you all know, Siglent produces oscilloscopes also for Atten, LeCroy...
I found that Atten ADS1102CML (Siglent of course) has that HW version!
So, is it possible that, whoever does this, built in 100MHz PCB, intended for Atten1102 into Siglent's 1072CML shell? What is more reliable: label on the scope (and "Siglent1072CML" on welcome-screen!) OR data from System status?
Is it possible that I will get Siglent 1102CML 100MHz scope in 1072's housing :D :D?
Of course I can't measure trise right now (frankly I'm not sure how to PROPERLY do this) - that would reveal actual BW ( if tr is less than 3,5ns =>100MHz -true?).
Also I want to "warn" you all - User Manual that comes with o'scope (and from net) is quite obsolete - no mention about time/date adjustments for example - you can find more recent data from appropriate LeCroy's User manual!
Any clue appreciated!

This 11-66-3.3 must be typing mistake.
I have SDS1072CML and 1102CML in stock.
Both models have HW: 11-62-3.3
System data and boot up screen tell you have Siglent SDS1072CML.
And its rise time is near 3.5ns and its -3dB BW is over 100MHz.
(in EEVblog forum you can find test result)

OK, thank you rf-loop! I will recheck this!
What did you mean under "typing mistake" - my cousin "misread" screen content or am I heard (and wrote to paper) wrong value (he repeated that numbers at least 3 times, because it was suspicious to me (I knew what I should expect)!) OR Siglent made typo in firmware?
...
EDIT: |O Please, SORRY, you meant that guys from amazon made typo? That's understandable.
But, can I ask you, since you have both o'scopes, if the hardware is the same (or the same HW version doesn't mean that PCBs and parts are the same?) is there any substantial difference between 1102 and 1072CML except 70/100 MHz bw (and 50 EUR more for 1102)?
--- Quote from: rf-loop ---And its (1072?) rise time is near 3.5ns and its -3dB BW is over 100MHz.
--- End quote ---
According to this, there is no reason to pay extra 50€ for 100MHz version!?
I will study now your link, thanks alot! :-+

They are same, exept analog front end BW..
Analog front end BW is different, but I do not know (read: I do not want take a position) how the difference have been made.
In some needs difference is "substantial" and in other needs difference is "big". It depends...
