Generalised Faraday rotation can induce frequency-dependent conversion between the linear and circular polarisation spectra of compact radio sources such as pulsars, fast radio bursts and active galactic nuclei. I devise a simple phenomenological model that can be used to measure the effects of generalised Faraday rotation on the linearly and circularly polarised spectra of these sources. The model is theory-agnostic, with an arbitrary wavelength dependence, and hence can accommodate for a variety of potential generalised Faraday rotation inducing media. It can also be combined with additional observables to infer the physical properties of the intervening medium.
