We discuss the use of a hysteretic Josephson junction to detect current fluctuations with frequencies below the plasma frequency of the junction. These adiabatic fluctuations are probed by switching measurements observing the noise-affected average rate of macroscopic quantum tunneling of the detector junction out of its zero-voltage state. In a proposed experimental scheme, frequencies of the noise are limited by an on-chip filtering circuit. The third cumulant of current fluctuations at the detector is related to an asymmetry of the switching rates.

Higher cumulants can in principle be taken into account in a similar manner, resulting in an asymptotic expansion around a Gaussian distribution. Furthermore, the restriction on γ can be avoided by direct numerical inversion of the characteristic function.
