The Tek 465/475 scopes are the best analog scopes ever made, IMHO. And
with the best analog triger
I think you might be able to get the cat eye to work on a sampling scope
by adjusting the persistence. At least that's what I would do with my
PicoScope.

Even our older Tek DSO does poorly with the analog alignment patterns...not just the "cat's
eye" radial alignment pattern, but also the azimuth bars. Index burst is "good
enough" on it and sometimes the ability to introduce large, precise trigger delays makes it
the more suitable tool (like for some alignments where we don't have the correct, factory-specified
AAD and have to calculate the index offset).
The old Tek 465 does excellent though :P
Thanks,
