Yup, I bought a an Agilent spectrum analyzer for my lab for a very
similar purpose.  New, the $35K price is probably close.  For
example, the Agilent E4404B good to 6.7GHz.  There is also a
a version good through 3GHz that would probably work for the 
2.4GHz ISM band.

See:

If you decide on a used version, then you should also consider the
cost of getting the calibration updated of you're making quantative
measurements which you'd like to be accurate.  You don't know where
some of the older gear has been, or how it's been treated.

This won't be of much use for measuring noise floors, or even seeing
the DS spread spectrum 802.11 signal.
