AM/FM IBOC Measurements with the N9340B
Application Notes
AM/FM IBOC, widely accepted as the next generation digital radio technology in many countries including US and Brazil, operates in conjunction with the existing analog AM/FM broadcast frequencies. The National Radio Systems Committee (NRSC) has published recommended standards that specify that IBOC signals, both Hybrid and All Digital, must be transmitted below the defined spectral emission limits. This requires broadcast engineers to perform spectral emission proof-of-performance testing during installation and routine maintenance. To help broadcast engineers complete those installation and maintenance tasks easier and more quickly, Keysight Technologies, Inc. offers the industry’s first dedicated IBOC measurement personality on the award-winning N9340B handheld spectrum analyz er, option N9340B-IBC. This document gives a brief introduction of IBOC technology and the benefits a user can realize from using the N9340B analyzer with the optional IBOC measurement personality.
