ACLR Limits
The Adjacent Channel Leakage power Ratio (ACLR) limits complement the spectrum
emission mask. The limits can be set in the configuration dialog, depending on the
channel bandwidth / the channel bandwidth combination.

The default values are identical for all bandwidths and for signals with and without car-
rier aggregation.
According to 3GPP, the relative limit shall be evaluated only, if the measured adjacent
channel power is greater than -50 dBm (absolute limit). In that case, the ACLR (that is,
