[time-nuts] Re: Getting phase noise data off an HP 3048A {External}

[Bob Camp]

HI

The real magic of the 3048A is all in the one “big box”. The counters, volt meters, spectrum analyzers
and the like that attach to that *could* be replace with just about anything similar.

Keeping all of those antique boxes running properly is a chore. Finding enough room on the bench 
for all of them is also a bit exciting. Something that would run the beast into a *good* audio analyzer
could go a long way towards breathing life back into that fine old setup. 

To bad the source code for that VB app is MIA.

It's challenging enough to use a 3048A without also having to deal with antique controller hardware and/or software, goof around with floppy disks and plotters, and so on.
