N2 - The measured spectral density of voltage noise in current-biased resistively shunted Josephson junctions in which quantum corrections to the noise are expected to be important is found to be in excellent agreement with theoretical predictions. The contribution at the measurement frequency of zero point fluctuations mixed down from frequencies near the Josephson frequency is clearly demonstrated.
