Phase Noise Tool
Overview
The Phase Noise tool allows users to measure phase noise in clock/oscillator sources. By simply choosing
the highest frequency to be displayed and the frequency resolution, the tool will measure and display the
phase noise spectrum. A summary view reports the phase noise values at common offset frequencies.
The Phase Noise tool is used to show the amplitude and frequency of phase noise relative to the carrier
signal frequency. This tool measures the fluctuations in the phase of a signal caused by time domain
instabilities. Fast and easy phase noise measurements of oscillators and PLL devices can be easily
correlated to other noise effects on the signal.
