Leakage makes it impossible to detect minor adjacent spectral components. The
following two figures refer to a slightly disturbed sine wave.
When you perform a Spectral Jitter measurement, it is likely that some degree of
leakage occurs. The measurement therefore provides a choice of FFT windows that
allow you to detect leakage and to reduce its impact.
An FFT window is a filter that sets the beginning and end of the time record
smoothly to zero. Such records can be seamlessly concatenated.
When you are using a window, please note:
• No window removes leakage completely.
