Normalization to 0 Hz Bandwidth
When you enter a Normalized Bandwidth of 0 Hz, the system plots the
measured noise data without normalizing it. Plotting the measured data
without normalization, causes all spurs, marked or unmarked to be plotted
at their true level in dBc. The criteria for marking spurs is a function of
the number of averages and the level of the spur. Spurs that were not
marked in a 1 Hz Normalized Bandwidth can be observed at their actual
level when there's no normalization of the noise.
When the measurement data is not normalized (0 Hz bandwidth), it is
plotted in the actual bandwidth in which it was measured. As a result,
breaks in the noise curve will appear at the band edges as shown in
Figure 4-1.
