The emission mask requirements are defined in 3GPP TS 36.141, section 6.6.3 "Oper-
ating Band Unwanted Emissions". The default values correspond to the emission
masks defined for a home BS and operating bands up to 3 GHz in section 6.6.3.5.2X.
The following tables provide an overview of these home BS requirements. Please note
that the stop frequency in the last row of each table indicates the implemented default
value. 3GPP instead defines f_offset
max
as stop frequency, which is "the offset to the
frequency 10 MHz outside the downlink operating band".

3.7.4 ACLR Limits
The Adjacent Channel Leakage power Ratio (ACLR) limits complement the spectrum
emission mask.
3GPP defines relative and absolute limits for several types of adjacent channel carri-
ers. The less stringent of the two limits applies. The test shall be performed with test
models E-TM1.1 and E-TM1.2 at maximum output power.
You can set the limits in the configuration dialog, depending on the channel bandwidth.
