John the problem is that all the software is specific to the 3561A so 
unless you are going to write your own version, you're stuck with the 
instruments that the 3048 software will address.  One exception is the 
Voltmeter, the later meters like the 34401A will work with the hpib 
commands for the 3478A.

The same applies to spectrum analyzers for the HF segment.

There are 3561As around, after a lot of searching I found not one but 
two, however both needed some work to get them running perfectly.

Personally I have had much more trouble getting the computer part of the 
system to work than I had with the  hardware, and I still have not 
managed to generate my own calibration files...

John Miles has some excellent pages on his site concerning the 3048A.
