Capture and compare means that a certain amount of incoming data is
captured and also compared with expected data in real time. The
number of captured data points is adjustable.
While the measurement is running, correct and incorrect data is
captured. The resulting records contain the captured data and the
corresponding error information.
These records are automatically processed. The error information is
subject to a fast Fourier transform (FFT). FFT reveals the spectral
components and their power. Several window algorithms are provided
to reduce the influence of leakage.
Jitter Distribution Over Time
Jitter has a more or less characteristic distribution over time.
The histogram of pure random jitter shows its Gaussian distribution, as
illustrated in the following figure:
