An economical way to measure phase noise using the PN2060A cross-correlation Phase Noise Analyzer
An economical way to measure phase noise using the PN2060A cross-correlation Phase Noise Analyzer Six weeks ago, I had heard of the phase noise of an oscillator but didn't really know what it was, much less how to measure it. In a short space of time, courtesy of Google and Youtube, I now know what it is, how to measure it and can measure it with an inexpensive phase noise analyser. In this post: 1 A brief summary of phase noise and how it is measured. 2 An overview of the PN2060A Phase Noise Analyzer, a low-cost instrument (US$480) available directly from Yanjun Ma BG6KHC in China, The instrument is a work in progress with new models available soon, but at a higher cost. 3 Using the PN2060A Phase Noise Analyzer to measure the phase noise of two modern spectrum analysers' reference 10 MHz and a CTI OCXO. All very easy after a couple of small hiccups as noted. In conclusion, the PN2060A Phase Noise Analyzer is an excellent, low-cost and easy-to-use instrument. What is phase n
