Frequency repack - monitoring group delay errors
The frequency reallocation will require stations to re-tune or even replace the output mask (band-pass) filters. Group delay measurements can help to set up and monitor the performance of the newly set transmission chain.
Detecting and monitoring inter-modulation products during spectrum reallocation
Stations might face unexpected problems related to inter-modulation interference during frequency repack.
In-band interference and DVB-CID decoding by AVQ1022DVBS
Even though signal interference in satellite broadcasting is a rare occurrence, it can be very costly to a satellite operator. Early identification of interference and its source should allow for a timely action to resolve the problem.
In-Band Interference Analysis
In-band interference can be caused by a number of sources, but most common would be the presence of an undesired signal source operating on the same channel assigned to an authorized user.
Changing Broadcast Environment Triggers Signal Monitoring and Analysis Challenges
Broadcasters around the world are adopting new transmission standards, while in the U.S., stations are preparing to move to new channel assignments, even as they eye single frequency networks as their ticket to reaching consumers moving around outside the home. All of these transmission changes open up new possibilities for in-band and co channel interference, and as engineers prepare to cope with those, they will also need solutions for dealing with the special monitoring needs of SFNs.
