Spectrum Analyzer Range Frequency Scanning
The Spectrum Analysis feature enables you to determine the noise characteristics per channel
per frequency range. When the Spectrum Analyzer feature is activated, the unit enters a
passive scanning mode for a period of time during which information is gathered. The scanned
channels are the channels comprising a selected subset.
Upon activating the spectrum analysis, the unit automatically shuts down the RF transmit
ports and keep eNB receive ports for capturing the data. During the information-gathering
period, the UEs will not be serviced by the eNB. At the end of the period, the user should
configure the system for normal operation.
The data is collected within a range of frequencies and on all active Rx ports (up to 4 ports), the
spectrum analyzer is aligned with the system configured TDD split, and the listening period is
in the uplink period.
