Signal Analyzer
bsw TestSystems & Consulting AG
The simplest way to measure the phase noise is to compare the Device-Under-Test (DUT) to the source of a spectrum analyzer. With the SA set at the same frequency as the OUT, you see the sum of the SA's and DUT's sideband-power spectrum on the SA display. It is a simple and straight forward method well suited for free running VCO's where the SA is easily an order better.You can improve on this method by establishing a Phase Lock (PLL) between the DUT and the Local Oscillator and create a zero-IF or base-band spectrum analyzer system.

90-Degree Optical Hybrid
Six-port hybrid devices have been used for microwave and millimeter-wave detection systems since the mid-1990s and are a key component for coherent receivers. In principle, the six-port device consists of linear dividers and combiners interconnected in such a way that four different vectorial additions of a reference signal (LO) and the signal to be detected are obtained. The levels of the four output signals are detected by balanced receivers. By applying suitable baseband signal processing algorithms, the amplitude and phase of the unknown signal can be determined.
