Hi Philip!

I am using 1661a for reverse-engineering a small

What kind of interface do you use? Wrote something 
similar for my 1661a based upon Solaris and gpib.

That sounds interesting! Does it mean, the analyzer 
does the operations? I know, that such software was 
available for these analyzers and I'd be interested 
in this stuff. 
Can the code be modified (e.g. is it possible to implement
an other CPU?)?

Depends on what communication library you used...

  Best reagrds,
