Hi folks,

I recently bought a used Tek SC 501 scope to plug into my TM500 series
rack. It is only a 5mhz unit and I bought it more for audio and afsk
type projects. The highest unmagnified writing speed is 1us/div and
with the X5 mag it's 200ns/div.

The crt beam seems very feeble at these two highest writing speeds.
Very unimpressive for what I would call Tek's normal high standards.
Not in the same ballpark as my SC502 dual trace unit for instance.

This unit is used and came from a GE lab environment. It perhaps
has thousands of hours on it, I'm not sure.

Were these SC 501 scopes just a dog or is my crt shot??

I notice the literature lists a very lame 1KV as the acceleration
voltage. That is pretty low for the job at hand isn't it?

Thanks to all who reply.
