hot key to analyze your measurements with the user-definable

Spurious emissions
Out-of-band emissions are unwanted emissions immediately outside the channel bandwidth resulting from
the modulation process and non-linearity in the transmitter but excluding spurious emissions. The Spurious
Emissions measurement is to identify and determine the power level of out-of-band spurious emission within
the necessary channel bandwidth and modulated signal measured at the RF port of the Base Station.
