Spectrum Emission Mask Measurement
Meas Setup
Meas Type
Accesses a menu that enables you to select one of the following measurement reference types:
• Total Pwr Ref – Sets the reference to the total carrier power and the measured data is shown in dBc
and dBm.
• PSD Ref – Sets the reference to the mean power spectral density of the carrier and the measured data
is shown in dB and dBm/Hz.
• Spectrum Peak Ref – Sets the reference to the spectrum peak power of the carrier and the measured
data is shown in dB and dBm.
Ref Channel
Accesses a menu that enables you to set up the measurement parameters used to calculate the power in
the reference channel.
Integ BW
Specifies the integration bandwidth used to calculate the power in the reference channel.
