Once an interfering carrier is found, the uplinking station can be contacted and a request may
be made to either disable or re-peak the identified transmission service.
A.4 Scenario 3: Partial Interference
Item Description
A “Interfering” 5.0 Msps DVB-2 Video Carrier
B “Desired” 3.5 Msps Data Carrier
Figure A-3. Scenario 3 (Partial Interference)
In the partial interference scenario shown here in Figure A-3, the energy of the interfering
carrier is significant. As shown here, the 5.0 Msps carrier partially interferes with the 3.5 Msps
carrier, and the resultant interference is significant enough that neither carrier results in usable
communication.
When the carriers have Carrier ID technology enabled, the MCxD-100 may be instructed to look
in the spectrum below the composite envelope to determine if Carrier IDs are present.
Once an interfering carrier is found, the uplinking station may be contacted and a request made
to disable the identified transmission service.
