Spectrum Analyzer
See Figure 3.2.23 . The carrier level is normalized to its unmodulated level at 0 dB. The graph center is
always at the carrier frequency, as defined by the Exciter’s set Frequency value.
Masks are shown based on transmission mode and are defined by the following standards:
 Analog AM standard: NRSC-2-B
 DRM and DRM+AM standards: ITU-R SM.328-11 and ITU-R SM.1541-4
 IBOC and IBOC+AM: NRSC-5-C
NOTE:
Any spurious emissions that are displayed are a product of the spectrum analyzer and are not
actually present on the transmitter output.
Click on the panel to display a cursor on the trace in the approximate area. The cursor position
(frequency and amplitude) is shown in the upper, right-hand corner of the panel. The center frequency is
shown in the upper, left-hand corner of the panel. Click in other areas of the spectrum analyzer panel to
provide a coarse adjustment of the cursor position.
