Is there any reason to use a preamplifier apart from the possibility that its noise figure may be better than that of the spectrum analyser? It seems unlikely that it would be much better than that of a CISPR receiver. Or do you mean a preamplifier at the antenna, to send a larger signal to the antenna cable and thus to the analyser or receiver? -- Regards, John Woodgate, OOO - Own Opinions Only. http://www.jmwa.demon.co.uk Interested in professional sound reinforcement and distribution?
