I have a 7904A with a 7A19 plugin (plus lots of slower ones, e.g. 7A24 and 7A26). I'd love to have two channels of > 500 MHz, and I'm contemplating if I should chase another 7A19 or get two 7A29 (and sell the 7A19). The 7A29 will make better use of the mainframe bandwidth and has a variable vertical deflection feature.
What I wonder: how do things look noise wise? I hate blurry traces, and I'm rather surprised how sharp the 7A19 is (much better than the 7A26!). Anyone who could compare them side-by-side?
Isn't that just due to the termination on the 7A19? Have you tried
putting a good inline termination on the 7A26?
Anyway, I haven't noticed a difference in trace noise between the 7A19 and 7A29.
