Measuring phase noise with a spectrum analyzer. The primary advantage of dedicated phase-noise analyzers. The cross-correlation method. Using a spectrum analyzer is the oldest, most straightforward, ...

Using a spectrum analyzer to measure noise signals requires several additional factors, such as sensitivity or how well the instrument can measure small signals. The analyzer’s noise floor specifies ...

Why You Can’t Just Use a Spectrum Analyzer Industry has an increasing demand for spectrally pure signals in applications such as imaging radar, mobile communications, satellite communications, weather ...

I recently had a discussion about measuring noise density (i.e., op amp noise) with a digital oscilloscope. While we certainly use oscilloscopes to measure time domain noise, as can be seen on nearly ...

Noise from the power supply, linear regulators, and voltage references is a major contributor to the limitations of system performance, especially in instrumentation and communications products. In ...

After extensive research of its customer base, Datastick Systems, Inc. claims that the noise floor of its handheld VSA Vibration Spectrum Analyzers may be the lowest in the industry. After extensive ...

Rohde & Schwarz has added a phase-locked loop based phase noise measurement capability to its FSU range of multi-gigahertz spectrum analysers. When measuring phase noise, the FSUP analyser compares ...
