Understanding IF Bandwidth In RF Signal Analyzers

Nettet1 Although many rule parts specify an emission bandwidth, defined as the bandwidth between points on the emission skirts that are 26 dB down from the fundamental power level, the occupied bandwidth is a more accurate and straightforward measurement and is acceptable to the FCC in lieu of the signal’s emission bandwidth. NettetCreating a single 2x GHz band standard would not be practical: to cover the entire 24.25 to 29.50 GHz range would require RF devices to handle a 5.25 GHz wide bandwidth. Therefore three bands were defined to cover the three geographical groups: n257: Covers 26.5 to 29.5 GHz for Japan, North America, and South Korea
