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.
Stations might face unexpected problems related to inter-modulation interference during frequency repack.
AVQ1022 and all new features will be presented at NAB Show New York, October 18-19. We invite you to visit our booth N818 for a demonstration.
AVQ1022 - RF Layer Monitoring Receiver brings new tools for echo profile monitoring in DAB/DAB+ SFN networks.
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.
