Spectrum Emission Mask compares the total power level
within the defined carrier bandwidth and the given offset fre-
quencies on each side of the carrier frequency against allowable
standards.
Adjacent Channel Power or Adjacent Channel Leakage
ratios measure RF power leakage in adjacent channels and its
ratios per specified standards.
The Spurious Emissions measurement identifies and deter-
mines spurious emissions power levels in certain frequency
bands.
RF Analysis
Channel Power measures a signal’s total RF power, spectral
density, and peak-to-average ratio (PAR) in a specified channel
bandwidth.
Occupied BW measures the frequency bandwidth contain-
ing 99 percent of the power for total integrated and occupied
power.
