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.

don't tend to work well with digital sampling scopes unless they have a large sweep
buffer and can keep the high speed sample rates at a slow sweep speed of a single full
revolution. I don't know of any cheap ones that don't change the sample rate with
the sweep rate.
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,
