Here are some quick tips from Greg Best of Greg Best Consulting on FM IBOC emission mask compliance measurement, whether you’re transmitting HD Radio with symetrical, or, someday, asymmetrical, sidebands.

Emission mask compliance measurement has six basic steps:

  • • Ensure enough dynamic range and proper test equipment setup
  • • Configure/optimize the transmitter and measure analog power and IBOC level
  • • Define measurement points and bandwidths
  • • Record data at each point
  • • Apply any correction factors necessary
  • • Compare emission measurements to FCC/NRSC emission mask

Best also discussed tips for optimum spectrum analyzer setup.

Best spoke at the IEEE Broadcast Symposium taking place in the Washington, D.C. area, which I’m attending this week.


The Basic Arguments

To begin the satellite hearing, Conyers asked, “If we are going to define the market as broadly as the merger supporters advocate, what kind of precedents are we setting?” He wondered how consumers who already have satellite radio equipment would be affected if the merger is approved. The FCC and Justice Department must review the proposal.
