Only through nitpicking you'll learn about the flaws. I'm not interested in how well something works on a sunny day, I want to know where the limits of a piece of equipment are.

A device without BNC inputs (and outputs) and proper case is not a real scope in my opinion.  Try using one on a daily basis...
OTOH, it is really useful little thing and I wish I had something like that when I was a kid... But it's a gadget.

nctnico:
There is a 'pro' version that has BNC connectors. But nothing stops you from adding connectors or a dedicated test fixture yourself. AFAIK the analog discovery has differential inputs. If so, you could create much better test fixtures then you can ever achieve on a common-ground oscilloscope.

Would be interesting to see if the newer Siglent instruments are significantly faster than the entry and mid level devices. This might hint at where the bottleneck is regarding speed.

Hehehehe.... ;)
I got a SDS1104X-E and my SDS2540X-HD at home, and access to a SDS2104X+ at work.
As I´ve tested the batronix demoboard, bodeplot with the 1104X-E was the fastest.
Could re-test it again, making sure the settings were all the same.

Yes you would need to, things like points # and autoscaling engaged could dramatically slow performance.

However all this my Bode plot is better than yours is nothing but hot air  :blah: without a standardized test !  :horse:

As a German cabaret artist once said, comparing times only makes sense if everyone starts at the same time. ;)
This can be reinterpreted according to the situation, always fits... 8)

In the meantime, I ignore such things as far as possible.
Do it yourself, experience it yourself, then you can say something meaningful about it.
