Phase Noise Measurement Overview

As wireless communication technologies evolve in the commercial and aerospace and defense industries, it is clear that the driver to meet demand for higher data rates, better spectrum efficiency, and lower power consumption is the digital technology, such as digital signal processing (DSP). It does not, however, devalue the importance of high-purity, high-stability signals—signal stability is fundamental to successful modern digital wireless communication systems. Phase noise is still one of the most important characteristics when evaluating the short-term stability of a signal. Pressure to bring products to market more quickly than ever does not allow time for executing multiple measurements across several instruments. An accurate, fast, and easy-to-use phase noise measurement tool is critical in the R&D and manufacturing environments.

A variety of measurement techniques have been developed to meet various requirements for phase noise measurements. The three most widely adopted techniques are: Direct spectrum, phase detector, and two-channel cross-correlation. Among them, the direct spectrum technique is the simplest and perhaps oldest technique for making phase noise measurements.

Keysight’s X-Series phase noise measurement application is based on the direct spectrum technique. The most obvious advantage using the direct spectrum technique for phase noise measurements is that it can be realized with a general-purpose signal/ spectrum analyzer. However, the analyzer’s settings, such as resolution bandwidth (RBW) and internal phase noise optimization loops, will need to be adjusted based on offset frequency to achieve the highest measurement accuracy and speed. Manually implementing phase noise measurements with a signal analyzer can be tedious and time consuming. The X-Series phase noise measurement application automates the optimization processes for the signal analyzer settings with one-button measurements without user interference.
