@Fungus:
Yes I could get the entry level Keysight scope. But what benefit would it offer me compared to any other scope on the list (and in particular: compared to a used MSOX3000)?
It obviously has benefits for Dave.
Dave likes it because it's the 'scope that never slows down no matter how much you throw at it, it's the 'scope for engineers who know the math, it speaks his language and does things the way he expects. Some might say it doesn't have much memory, and that's true, but it has a few tricks up its sleeve and seems to get the job done anyway.
(Some might say that "Deep memory" is a FUD term thrown around by salesmen, there's some truth in that, too, and I can remember those exact same salesmen saying so when the Rigol DS1054Z appeared with a lot more memory than
their models had at the time)
Me? I'd probably get the GW-Instek because:
* I know it's technically good (electronically and mathematically)
* I'm sure all the features will work properly and there won't be much it can't do
* It has a separate button for menu selections (no pushing of the twisty knob)
* Separate vertical controls for each channel (no messing about with multiplexed buttons).
* Fast and responsive
That's a personal choice though.
Now excuse me, my new oscilloscope just arrived. I've an unboxing to do...
