The diagram shows the power of the inverse equalizer coefficients for all subcarriers.
The results are normalized to the arithmetic mean value of the results. Hence the mea-
surement curve is centered around the 0 dB line.

3.8.5 Detailed Views: Spectrum Emission Mask
The spectrum emission mask results are displayed in a diagram and as a table of stat-
istical results. Additional margin results can be shown/hidden via hotkey.
Fig. 3-16: LTE eNodeB Multi Evaluation: Emission Mask
The measurement covers a symmetric frequency range around the center carrier fre-
quency.
Resolution filters with bandwidths of 30 kHz, 100 kHz and 1 MHz are available. Traces
for all three resolution bandwidths (RBW) can be displayed in parallel, with the 30 kHz
continuous trace at the bottom, the 1 MHz trace on top and the 100 kHz trace in-
between. In the figure above, the 100 kHz trace is present for carrier offset frequencies
from 5 to 15 MHz, the 1 MHz trace for offset frequencies beyond 15 MHz.
The frequency ranges of the 100 kHz and 1 MHz traces are determined by the active
limits using these resolution bandwidths. Thus these traces are only available for out-
of-band frequency ranges, with a gap for the inband frequencies. These traces can
also be hidden completely if not used at all by the active limits. Or they can be dis-
played as discontinuous traces with many gaps if the limits are defined in this way.
