Thanks very much!

Rick would be a very good source.

I have not worked with one enough to know about that; but, from what little 
I have seen, wonder if the display capabilities could match the real-time 
graphing of the B&K...That's why I was wondering if there might be some way 
to hook the analyzer up to some kind of special purpose video 
display...something like engineers might use for modeling.
