Practical Solutions for Measuring Phase Noise - RF CafeAugust 11, 2020 - Vista, California - Axiom Test Equipment, an electronic test equipment rental and sales company has published a new blog post entitled "Practical Solutions for Measuring Phase Noise" that examines phase noise, what it is, why too much noise and frequency instability can be a problem in testing, and how to find the right method and equipment for measuring it.

Phase noise can often be measured directly using different measurement approaches such as residual and cross-correlation techniques, which are explored more in-depth in the blog. Most importantly, the blog explains what specifications to look for in a spectrum or signal analyzer to ensure the best fit for the job. A few equipment examples are given as guides.

Practical Solutions for Measuring Phase Noise

August 03, 2020

It is part of the performance of almost every signal source, even active components, such as amplifiers. It is phase noise, and, at sufficiently high levels, it can prevent a radar or communications system from operating effectively. Fortunately, it can be measured quickly and accurately constant improvements in test hardware and software are making the task of determining a high-frequency source's phase noise easier even as signal bandwidths continue to reach into millimeter-wave frequency bands.

What is phase noise?

Phase noise consists of fluctuations in the phase of an oscillator, frequency synthesizer, or other signal source as measured in the frequency domain. It is also known as jitter when it is associated with timing deviations in a system clock. A sine wave without noise or change in frequency would go from one period to the next without variations in phase or amplitude. However, real-world signals exhibit some deviations in phase and amplitude which can occupy more of the spectrum than originally intended. Too much noise can be problematic, for example, in a crowded communications spectrum or an operating environment with many closely spaced channels or communication signals, where the noise can block or obscure some signals from reaching an intended receiver. The phase/frequency instability can also cause errors in communication systems that transmit and receive signals based on phase or frequency modulation.

How can it be measured?

Fortunately, the phase noise of a signal source can often be measured directly, with one of the most versatile of high-frequency instruments, the spectrum analyzer. The phase noise of a source is usually expressed as the amount of signal power within a 1-Hz bandwidth at some offset frequency from the carrier frequency (dBc/Hz). Because a real-world signal will deviate above and below a nominal tuned carrier frequency with some variations in amplitude and phase, it can fill more of the frequency spectrum than intended. On a spectral plot, phase noise appears as sidebands above and below the carrier and is measured and calculated as the single-sideband phase noise—the amount of noise contained within a 1-Hz bandwidth lying at a specific spectral distance from the carrier frequency.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
