Peaks over 1Ghz are measured with the average detector function of the measurement device activated. Bandwidth and amplitude criteria can be viewed in FCC document 47CFR - Part 15, Section D and Part 24. For acceptable techniques at making average measurements or measurements above 1Ghz, refer to ANSI C63.4-1992. Another good reference guide is the FCC's 1995 memorandum entitled "Guidance on Measurements for Direct Sequence Spread Spectrum Systems". It describes methods for making average measurements. Siegfried Linkwitz of Hewlett-Packard's Signal Analysis division (in 1987) wrote two articles titled "Measurement of Narrowband and Broadband Emissions using Peak and Average Detection" (for the 1987 IEEE Symposium) and "Using a Spectrum Analyzer to Measure the Narrowband Content of an Emissions Spectrum". I have copies of these documents somewhere. If you would like copies, send me an email and I will fax them to you. Bandele Jetstream Communications, Inc.

(FCC) The EUT is a AMPS/PCS cell phone. Are signals over 1000 MHz measured in Peak or Averaged!
