RF Spectrum Example Select RF Spectrum Analyzer feature from the main feature screen: 26 (EMF-380 V2, EMF-390 Models) (EMF-360+ V2 Model) RF Spectrum Analyzer (Except EMF-360) From above screens: Total power: 458 picowatte Peak: -57dBm @ 2.402GHz Minimum: 0.398 picowatte Frequency checked scope: 2.400GHz – 2.504GHz Channel step: 405 KHz Channel bandwidth: 812KHz At user cursor location: -90dBm @ 2.459GHz Lowest power detected @ -93dBm 27 RF Spectrum and RF Browser (Common Question) Some may be confused between the function of RF Browser and RF Spectrum Analyzer of GQ EMF-390. A quick answer would be the RF Browser is to detect the total amount of RF radiation, from all sources that have the frequency bands between 0.01GHz to 10GHz. (See graph 1) The RF Spectrum Analyzer is an advanced feature to test the strength of RF radiation in specific range of frequency bands. For example, we could use it to test the amount of RF radiation, only between 2.4GHz to 2.5GHz. (See graph 2) In conclusion, our GQ EMF-390 could detect the total RF radiation up to 10GHz; and several ranges of frequency bands up to 2.5GHz if you wish to detect only the specific range of frequency bands with RF Spectrum Analyzer. 28 USB Driver Windows 1.
