2-22 Spurious Emissions (Out-of-Band)
The Spectrum Analyzer measures spurious emissions from a base station using the Spurious
Emissions (Out-of-Band) Mask feature. Creating a spurious emission mask allows you to test
signals against wireless communications standards. A mask with up to 32 segments must be
created before starting the measurements.
