Phase Noise Testing
Quick phase noise tests can be made with a spectrum analyzer, and many spectrum analyzers have built-in phase noise measurement capability. But often times the phase noise requirement of the signal source under test exceeds the performance of the particular spectrum analyzer that might be available in your lab.
Phase noise testing is likely to be a performance test that only needs to be done occasionally, during development for example, and is not necessary on a routine unit-to-unit basis. It doesn't make sense to have a $70k+ test instrument sitting around idly in your lab.
Since phase noise analysis is a vital part of what we have to do in developing our signal source products, we have invested in the equipment to do the job. We routinely use test and optimize our products using our Berkeley Nucleonics 20GHz signal source analyzer.
We can make phase noise measurements on your product too and provide you with tabular data, PN offset frequency plots, and jitter analysis. We can also help you improve your system by offering suggestions and showing you how to improve your product’s phase noise and stability.
