With carrier aggregation, RBs are allocated for the PCC, but not for the SCC. The lim-
its apply to both component carriers. The measurement displays inband emission
result diagrams for both carriers.

Equalizer Spectrum Flatness Limits
For EVM measurements, an equalization step has to be performed after the FFT. The
spectrum flatness of this equalizer has to be verified to validate the EVM results.
For equalizer spectrum flatness measurements, 3GPP divides each frequency band
into two ranges. For normal conditions, range 1 contains the subcarriers with at least 3
MHz distance to the band edges, while range 2 contains all subcarriers within 3 MHz
distance to the band edges. For extreme conditions 5 MHz instead of 3 MHz are speci-
fied.
The conformance requirements define limits for the maximum power variations within
each range and between the ranges. These limits are listed in the table below. The fol-
lowing figure illustrates the limits for normal conditions.

The limits and the band edge distance can be set in the configuration dialog, depend-
ing on the modulation scheme.
