Phase noise and AM noise measurements in the frequency domain
Abstract
The fundamentals and techniques for measurement of phase noise are set forth for two basic systems. The two-oscillator technique provides the capability for measuring high-performance CW sources. The system sensitivity is superior to the single-oscillator technique for measuring phase noise very close to the carrier. The single-oscillator technique employing the delay line as an FM discriminator has adequate sensitivity for measuring most microwave sources; it has several advantages: only one source is required, phase-locked loops are not required, system configuration is relatively inexpensive, and the system is inherently insensitive to oscillator frequency drift.
