Modes in the third harmonic cavities, designed and fabricated by FNAL, are analysed and the sensitivity to frequency errors are assessed. A circuit model is employed to model both monopole and dipole bands. The monopole circuit model is enhanced to include successive cell coupling, in addition to the usual nearest neighbour cell coupling.
