There is only one problem: there are no "new scopes" that will
substitute for a 485/7904 for some purposes of work on analog signals.
Period. They don't exist.

The Lecroy people proved this false when they were selling Iwatsus
here. The converter tube Iwatsu does everything a 485 does, but
backwards and in high heels, plus gives you VGA and digital image
storage.
