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.

This won't be of much use for measuring noise floors, or even seeing the DS spread spectrum 802.11 signal. louie To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-mobile" in the body of the message
