Measuring these oscillations as a function of magnetic field and gate voltages, we describe three signatures that distinguish the two types. The oscillations observed in a $$2.0\mu m^2$$ device are understood to arise from a Coulomb blockade mechanism and those observed in an $$18\mu m^2$$ device from an Aharonov-Bohm mechanism. This work clarifies, provides ways to distinguish, and demonstrates control over these distinct mechanisms of oscillations seen in electronic Fabry-Perot interferometers.
