Guys
This is, first of all, a crappy scope. Its sampling rate is 20Ms at claimed bandwidth of 500MHZ. Which means that even if amp bandwidth should be adequate A/D converter is not.
At work while in Telecom I had a 16GHz 4 channel Tek with full software (eye analysis, all hystograms etc) - you should see the waveform, it is beautiful.
I also have a 1GHz GP Tek scope at work now, bought it 2 years ago, also a great scope. But then this HP is from 80s - it is about 30 years old.
I do not see todays good digital scopes being any worse the analog. If anything they are better. Their brightness is no longer dependent on the time base as it was the case with all analogs, and of course triggering is vastly superior so this hideous memory phosphorus that was in analog memory scopes is no longer needed. I grew up with analog scopes but once I tried a good digital one, I switched in a jiffy, no nostalgia at all.
