Not in the same ballpark as my SC502 dual trace unit for instance.

Are you triggering the sweep at the higher speeds or just letting it
auto-trigger? Auto-trigger is done at a low rate and makes the sweep
very dim until it gets an actual high frequency trigger.

Bill, I know exactly what you are saying and I was triggering from
a sinewave signal generator at rates from 1mhz to 10mhz where the
scopes bandwidth becomes the limit of usability.

Most Tek scopes produce a trace that looks like a green laser beam.
This thing is like a 2AP1 or 2BP1 and lacks that normal Tek punch,
but as mentioned, it only has 1kv of acceleration potential so I am
guessing lame is the name of the game.
