The frequency domain representation of a waveform shows the distribution of signal strength at different frequencies. The Fourier transform can convert time-domain signals into frequency-domain signals, showing the frequency components and their strengths in the signal. Phase fluctuations are change... read more

Understanding phase noise and jitter is essential in the fields of telecommunications, electronics, and signal processing, as they both represent imperfections in signal timing that can affect the performance and reliability of systems. Phase noise is the random fluctuation of waveform phase, affect... read more

Testing OCXO and TCXO for phase noise and jitter involves specialized equipment. Phase noise is measured with a phase noise analyzer or spectrum analyzer, while jitter is measured with a time interval analyzer or oscilloscope. For phase noise measurement, the oscillator output is connected to the an... read more
