Phase Noise Plots Without Phase Noise Impairment
The Agilent X-Series vector signal generator
demonstrates a definitive shape to its phase
noise plot. The mid–frequency offsets are
characterized by a leveling (flattening) of the
phase noise amplitude from approximately a
3 kHz offset to approximately a 70 kHz offset.
Close in and far out offsets demonstrate
sloping characteristics (areas before and
after the mid–frequency offsets).
The signal generator degrades the phase noise by moving the mid–frequency characteristics and/or
changing its amplitude using the following settings:
• Start frequency (f1) of the mid–frequency characteristics
• Stop frequency (f2) of the mid–frequency characteristics
• Amplitude (Lmid) of the mid–frequency characteristics
