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, Jonathan
