An experimental method for determining the second-order coefficient (β) of the nonlinear conductance of a Gunn diode oscillator is presented. This is obtained in a novel way by utilising the dependence of the device characteristic on the frequency response characteristic of an injection locked oscillator. β is found to be bias dependent and the measured values corroborate the theoretical findings.
