- Abstract
- The stability of the time base of an oscilloscope has been analyzed by digitizing sinu-
soidal signals from precision sinusoidal voltage generators. Frequency domain analysis
of the recorded data has been performed using the Fourier transform routine built into
the recording device, after suitable windowing. Due to the stability of the frequency of
the used signals, the expected frequency spectra would be Gaussian functions due to
any uncorrelated noise born in all devices connecting the voltage signal generator to the
memories of the oscilloscope. The experimental power spectra present instead a non-
Gaussian shape, mainly in the points far from their mean values, showing raised \skirt\",
which a pure Gaussian function is clearly unable to t. Among the many \deformed\"
Gaussian distribution functions, those named q-Gaussian and ?-Gaussian respectively,
from the symbols used for the characterizing parameters, are instead in good agreement
with all experimental power spectra. These results can be attributed mainly to correlated
drifts in the time base of the oscilloscope. (literal)
