Phase Noise / Jitter Testing Service Booking

Phase Noise and Jitter Testing are critical assessments performed on oscillators and signal sources in the field of electronics and telecommunications. These tests help determine the quality and stability of a signal, which ultimately impacts the performance of the overall system.

Phase Noise: This refers to the frequency domain representation of rapid, short-term, random fluctuations in the phase of a waveform, caused by time domain instabilities. Essentially, it's the noise that you see on a signal when you look at it in the frequency domain. A lower level of phase noise is desirable as it indicates a more stable and clean signal. Phase noise can be caused by various factors like temperature, load impedance, power supply noise, or vibrations. It is commonly measured in dBc/Hz at a certain offset from the carrier frequency.

Jitter: Jitter, on the other hand, is the time domain representation of the same phenomena. It refers to the small, rapid variations in a waveform's timing that occur due to noise, interference, or clock recovery. These variations can lead to errors in data transmission, especially in high-speed digital systems. Jitter is typically measured in units of time (e.g., picoseconds).

Phase Noise and Jitter Testing: These tests measure the stability and quality of a signal by quantifying its phase noise and jitter. The testing process involves comparing the output of the device under test (DUT) against a reference clock with known performance. The results of these tests can help engineers identify and address potential issues that could impact system performance.

In essence, phase noise and jitter are two sides of the same coin, representing frequency instability in the frequency and time domains respectively. Both need to be minimized for optimal system performance.
