RF Spectrum Analyzer mode: detects RF radiation in specific range of frequency bands, such as, 50 to 65MHz, .... up to 2.5GHz **Q: Why does the spectrum analyzer have a large gap in its frequency range between ~1ghz and 2.4ghz?** A: The RF Spectrum Analyzer is an extra bonus feature besides the RF detector up to 10Ghz on EMF-390. Due to the cost constraint, the RF Spectrum Analyzer mainly focused on popular RF bands. **Q: Does it teach you the particular emf pattern of a ghost? lol** A: This is the EMF meter. We have GQ Ghost meter detects ghost pattern. From small ghost to big ghost.
