Fig. 3-9: Spectrum emission mask limit settings
The mask is defined as described in the following tables. The corresponding
R&S
CMW settings (points and lines) are indicated.
These requirements are defined in 3GPP TS 34.121, sections 5.9 "Spectrum Emission
Mask, 5.9A and 5.9B.
The first table lists a relative requirement (dB relative to carrier) and an absolute
requirement (dBm). The higher of the two power limits applies.
Additionally the requirements in the subsequent tables have to be fulfilled, depending
on the operating band. When you select an operating band with additional require-
ments, the "Line H Mode" is set automatically (a manual override is possible). The
mode determines the frequency offset range to be used for the limit check (first column
of the tables) and the measurement bandwidth (last column). The limit value settings
(second column) are not influenced by the line H mode and have to be set manually.
