Bob, This is Power Spectral Density. By definition it is the Fourier transform of the time-averaged autocorrelation function of the signal.
I haven't performed the measurement before, but I believe it is not distance specific since the power is normalized and is best to measure direct conducted. Quick search I found the below link for measuring on the Agilent website. http://www.home.agilent.com/agilent/faqDetail.jspx?cc=US&lc=eng&ckey=740009&nid=-11143.0.00&id=740009 Hope that is helpful. --- [email protected] wrote: > I am reading a Japanese standard for 2.4 GHz and it > gives an "antenna > power" limit of 3mW/MHz (no antenna distance).
