. The carrier level is normalized to its unmodulated carrier level at 0 dB. The graph
center is always at the carrier frequency, as defined by the active preset’s Frequency value.
Masks are shown based on transmission mode and are defined by the latest versions of the following
standards:
•
IBOC: NRSC-5
•
European Standard: ETSI EN 302 018-2
•
FCC CFR 47, Part 73.317 and IC BETS-6e
Note:
While very accurate, the spectrum analyzer may display artifacts (spurs) as some operating carrier
frequencies that are a function of the analyzer and are not actually present on the output of the
transmitter. If these spurious emissions are observed on the spectrum analyzer, Nautel
recommends that a calibrated, external spectrum analyzer be used to verify the presence of spurs
.
