Spectrum Emission Mask
Spectrum Emission Mask measurement includes the in- band
and out- of- band spurious emissions. As it applies to
W- CDMA (3GPP), this is the power contained in a specified
frequency bandwidth at certain offsets relative to the total
carrier power. It may also be expressed as a ratio of power
spectral densities between the carrier and the specified
offset frequency band. For WLAN, the reference power is
taken as the peak PSD in the signal, and all offset results
are also the peak PSD in that offset as opposed to the
integrated power.

Avg Number
On Off
Set Avg Number to On to specify the number of measurement
averages used when calculating the measurement result. The
average will be displayed at the end of each sweep. Setting
Avg Number to Off disables measurement averaging.
