Cats eye 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,
