4.2.1 User-defined mode

In this case, the Blocking is provided in dB and represents the attenuation of the receiver at a given frequency offset (see A8.7). The resulting receiver attenuation equals the user-defined input values. Then, the iRSSblocking at the interferer operating frequency  may be calculated as follows.

(Note: The ILT bandwidth is not considered in the iRSSblocking  calculation):

                                                                          (Eq. 22)

                       

  

This can be checked by running a simulation and displaying the iRSSblocking in case of User-defined mode calculated by SEAMCAT. See the figure below.
