Phase Noise Level of Various Agilent Sources
The graph in Figure 290 indicates the level of phase noise that has been
measured for several potential reference sources at specific frequencies.
Depending on the sensitivity that is required at the offset to be measured, a
single reference source may suffice or several different references may be
needed to achieve the necessary sensitivity at different offsets.
