Re: SUCCESS! The "sick" 475A is now the "fixed" 475A!


As this is just a hobby (at the moment, aside from trying to decipher display control signals in an old laptop, I basically just play with different entertaining scope features), and the big thing that I can't currently do is generate signals of a high enough bandwidth to actually observe the rolloff on any of my scopes (not even the 2213 or 2215A). I'd really like to be able to see the 3 dB attenuation when we get up to the scopes designed bandwidth (or to verify that the scope isn't making it up that far, as with the 475A that still seems to need some work). I've seen RF signal generators quite cheap on eBay (like this or this would one of these be at least able to exercise my 475/475A in an interesting way?
