Anybody who has bought a MSO1074Z and wants to share some experiences? Hopefully the PCB board there is also a clean design, without any last-minute fixes and wire bridges.
Regarding the CPU in MSO1074Z and MSO2072A. Is there a big difference in performance?
What does the MSO2072A have, that the MSO1074Z does not have?
Is it correct that it is only a bit faster, has deeper memory, and can handle higher bandwidth?
For one thing, the MSO2000A does up to 2GSa/s, where the MSO1074Z tops out at 1GSa/s.
(If you actually want to use more than 2 channels, this tops out at 250MSa/s)
So 300MHz is really only achievable if you're running 1 channel only.
But if you do not need the higher bandwidth and the deeper memory, it is probably better to go for the 4 channels right?
Patching the MSO1074Z up to 300 MHz, and going for the optional increased memory depth, should be more than enough for my expected application area,
and I really appreciate the 4 channels.
If you don't need the higher bandwidth, why bother with the 300MHz?
When using more than 1 channel, you Nyquist frequency is at 250 MHz (125Mhz for more than 2 channels), meaning that all that extra bandwidth is used for aliasing high-frequency noise and signals...
I find that, for most of my (mainly digital) design work, the 16 digital channels more than make up for the fact I have only 2 analog channels...
In my opinion, if you can swallow the price difference and don't absolutely need more than 2 ANALOG channels, go for the MSO2000A series...
Just my $0,02
