-cycle. Result is D ( D 1) 5. Power density is defined by Pd (mW / MHz) = P / [D x S] since it is defined as the average power density within the transmit burst If you need more information, don't hesitate to contact me: Theo Hildering Product Assessor Certification Consultant QA documents

mw/mhz

I am reading a Japanese standard for 2.4 GHz and it gives an antenna power limit of 3mW/MHz (no antenna distance). Can someone help as to how this is measured. I guess I don't understand the parameter being measured. Thanks Bob Heller 3M Company St. Paul, MN 55107-1208 Tel: 651- 778-6336 Fax:

) and then backwards determining the EIRP, but am not sure if this standard has that provision. Hope that helps. Larry Stillings Compliance Worldwide, Inc.

Re: mw/mhz

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

Re: mw/mhz

Bob From my (limited) experience with Japanese radio testing, even for low power devices, all measurements are made via a direct measurement at the antenna port. In this case the measurement would be made using a resolution bandwidth of 1MHz and the limit is 3mW (4.8 dBm). There is also
