Never having owned a decent scope before, please help me out a little.
Well, I do have a 60mhz Hickok that's really beat up.
If I want to get up to 500 MHz (70 cm is 400+ right?) I could try to
locate a 7A29, or maybe there's another cheeper one? That's question
number 1.
2. Sounds like one definitely has to have a better timebase plugin,
you seem to be implying that, to make use of the bandwidth of the
7A29, right? Which one, you list three. Or any of the above?
For my 7104 1GHz scope, I have 2x7A29 for vertical inputs, and a
7B10/7B15 timebase pair for horizontal (standard + delayed sweep).
For a 7904A, 2x7A19 is all that is really needed for vertical (it is a
single 50ohm input 500MHz amp) plus a 7B92A gives you normal + delayed
sweep. This leaves an extra horizontal slot open.
7A19s are usually readily available on eBay, and 7B92As are pretty
common as well.
