3.9 SEM Measurement
ETOCenter
From the lowermost carrier center frequency - spacing of this carrier /2 (for
lower offset), the uppermost carrier center frequency + spacing of this carrier /2
(for upper offset) to the center frequency of offset measuring filter*
ETOEdge
From the lowermost carrier center frequency - spacing of this carrier /2 (for
lower offset), the uppermost carrier center frequency + spacing of this carrier /2
(for upper offset) to the nominal -3 dB point of the offset measuring filter* closer
to the carrier
RTOCenter
From either the lower or upper RF BW** edge frequency to the center frequency
of offset measuring filter*
RTOEdge
From either the lower or upper RF BW** edge frequency to the nominal -3 dB
point of the offset measuring filter* closer to the carrier
RCTOCenter
5G NR Mode only
From the center frequency of RF BW to the center frequency of offset measuring
filter*
*Measuring filter = Meas BW (N) x Res BW
** RF BW = BW

which is defined in each 3GPP standard, regardless of
“Measure Carrier” for the uppermost and the lowermost carriers being Enabled or
Disabled. When Number of Component Carriers = 1, RF BW = BW
