So I bought the 2072A-S Version.
To answer my own question: Yes, it is possible, to unlock all the Options also on this version. Got the 300MHz B/W and all Memory/Trigger/Decode options. The Signal Generator still works just fine and the 50Ohm input impedance also works.
But to answer your questions, here are some negative experiences I made with this device so far:
- It's pretty loud. I use it at home in my room, so there are no other devices making noise except my PC. But in comparison to the PC, which is nearly not hearable, the scope is really a bit annoying. Since there is no Fan-Control at all, the fan is always at full speed, also if I just take one snapshot every minute. When I'm really working on something and have to scope running for more than 15 minutes, the fan noise really starts to piss me off.
- The controls are pretty un-intuitive. It has so many buttons and nobs but still I can't say, it's easy or unintuitive to set this thing up. This is the same for the Scope part as for the Signal-Generator part. I don't like the haptics of this instrument at all. The Buttons are pretty squishy and the small rotary knobs feally pretty cheap.
- The Signal Generator is not sweepable. Of course you can use the rotary knob to sweep it, but that is not what you want to.
- Of course it is Made in China, but there are to many parts of the instructions or datasheets full of chinese symbols, you could think this device was actually meant for the asian market.
In conclusion: Besides the nice specs for this price in terms of screen resolution, memory, Bandwidth, I'm not sure, whether I will keep it or not.
It just "feel" pretty cheap for a 1100€ device (1500$).
