[Test-Equipment] Oscilloscopes

[Edward J White]

Hi Gang:
Wile on the subject of oscilloscopes what is the difference between the 
digital and analog scopes? I read  speed or should we say bandwidth of 1GHz. 
will this work at 1 GHz RF or are we talking speed of a digital signal of 18 
or less v P/P.
What is some recommendations for a good RF scope?
