Noise Diagram
The "Noise Diagram" result display shows the power level of the noise over a variable
frequency offset from the carrier frequency.
The unit of both axes in the diagram is fix. The x-axis always shows the offset frequen-
cies in relation to the carrier frequency on a logarithmic scale in Hz. It always has a
logarithmic scale to make sure of an equal representation of offsets near and far away
from the carrier. The range of offsets that the x-axis shows is variable and depends on
the
measurement range you have defined and the scope of the x-axis that you have
set.
The y-axis always shows the noise power level contained in a 1 Hz bandwidth in rela-
tion to the level of the carrier.
