3.7 Additive Phase Noise Measurement
The additive phase noise measurement tab provides single- or two channel cross-correlation additive
phase noise measurements on non self-oscillating devices such as amplifiers in linear and non-linear
operation or even frequency-translating devices such as mixers, frequency multipliers or dividers.
The measurement principle is based on the assumption that the phase noise of the stimulating signal
of the DUT (external reference source) is completely cancelled out when manually adjusted to phase
quadrature. For the measurement setup, an external phase shifter and power splitter is required for
each measurement channel. A suitable external low-noise reference source (stimulus) must be used.
After switching into the corresponding tab, the GUI appears as shown in Figure 16.
