So I don't have the MSO-28, I have the MSO-19 which is approximately the same except it is one analog channel.
This meter is a waste of money.
Now I'm not saying that it doesn't work because it does and it does work as a scope. What I am saying is that it is ridiculously overpriced when you can get a Sigilent scope for the same price.
Some measurements I tested on my scope:
60MHz analog bandwidth!! Laughable. 60MHz/200MSa/s = 3 samples per waveform!! Really this scope is completely useless over about 20MHz.
A spec not given is the capture rate. I clocked mine at a whopping 6 waveforms per second. You read that correctly, not 6,000. Not 60,000. 6.
Also, 1GSa/s is only in repetitive mode, not real-time capture. That is limited to 200MSa/s.
The serial decode doesn't really work. It sort of does, but gets hung up and isn't reliable to say the least.
Compare all of this to the SDS1202X-E: https://store.siglentamerica.com/product/sds1102x-e/
Do what I should have done and buy a real scope.
No public wish lists :(
