[Amps] Advice on instruments for ham use

[Gary Smith]

My first reason for wanting a scope is to see my output signal.  And, as Colin,  K7FM has noted ( i think this is a very good idea) I will be able to look at the xcvr output vs. what's coming out of the amp.

Now I'm on the hunt for a good working`scope, I am.

Again my thanks to the never ending wellspring of knowledge to all of the members this list.

  To expound a little further on analog vs digital:

  Analog scopes are fine for a repeating waveform such as RF, or one
  which changes relatively slowly such as an audio frequency voice
  trace.

  Digital scopes are best for a one-time event which is either too fast
  or too slow for the human eye to capture well.  One example would be
  capturing a relay or switch contact bounce.  They also (usually) have
  the ability to store and print out individual traces.

  Each has their place, but for amateur radio purposes, an analog type
  is probably adequate, as well as easier to fix and cheaper to buy.
