Occupied bandwidth
The Occupied Bandwidth measures the percentage of the transmitted power within a specified bandwidth. The percentage is
typically 99%.
Setting measure setup
After configuring spectrum measurement in "
Configuring Spectrum Measurements
", you can set the measure setup to continue your
measurement. The measurement settings can be saved and recalled as a file by selecting File Type as Setup and load the file onto
the instrument using the
Save/Load
icons on the side bar.

Occupied bandwidth with DSS Analyzer
The Occupied Bandwidth measurement shows both of power across the band and power bandwidth in a user specified percentage
to determine the amount of spectrum used by a modulated signal. Occupied bandwidth is typically calculated as the bandwidth
containing 99% of the transmitted power.
Spectrum emission mask
The Spectrum Emission Mask (SEM) measurement is to identify and determine the power level of out-of band spurious emission
outside the necessary channel bandwidth and modulated signal. It measures the power ratio between in-band and adjacent
channels. The CellAdvisor 5G indicates either Pass or Fail based on the specified limit of the signal.
