Hi egonotto,
I´ll have fun with it..
When the SDS3034X HD arrives, the 804X HD will probably sold again, I wouldn't know what else to do with it.
Until then, I will take measurements and present them here, different situations, sometimes with and sometimes without the demo board.
Noise test with microphone too, bandwidth measurements, staggered according to original, 100Mhz, 200Mhz.
Then see if the upgrade to the 824 really means 100Mpts memory, stuff like that.
I like to try out scopes myself instead of watching videos or reading threads and the price makes it easy to realize this.
I have no doubt that I'll get rid of it quickly when the time comes.
