Definition of Measurement Error Sources and Terms used in Calculations (continued) Phase Noise and Allan Deviation The input signal’s jitter spectrum (Phase noise) and low-frequency wander characteristics (Allan variation) will limit the achievable measurement resolution and accuracy. The full accuracy and resolution of the counter can only be achieved when using a high-quality input signal source or by externally filtering the input signal to reduce these errors.
