Phase noise can be a limiting parameter for many types of systems. As radar precision, data rates and modulation complexity increases, low phase noise oscillators and instrumentation to accurately generate and measure extremely low phase noise has never been more important. This workshop focuses on how to generate signals with low phase noise and how to perform accurate and fast measurements. We will contrast different techniques, such as the direct spectrum analyzer-, phase detector-, phase detector with cross correlation- and delay line discriminator method. Each has a different level of cost, complexity, measurement speed, and ability to attain a certain accuracy.
We will also introduce a new technique using direct down-conversion, analog I/Q mixers and baseband signal sampling that provides extremely high measurement sensitivity and speed. It allows to measure phase noise as low as -183 dBc/Hz with a 100 MHz carrier frequency and 10 kHz within two minutes. CW, Additive and Pulsed Phase Noise, Pulsed-Additive Phase Noise, and AM Noise measurements can be performed as easily and simultaneously.
