The paper presents a rotational single sheet tester, which can be used to measure vector hysteresis characteristics using specimen with round shape. The measured hysteresis characteristics in the two orthogonal directions present the uniaxial anisotropy of the material under test, which has been handled by the Fourier expansion of the measured Everett functions. The Fourier coefficients of the unknown vector Everett function have been identified by the modification of a previously implemented algorithm. In the identification task linearly and circularly polarized measured data have been taken into account. Comparisons between measured and simulated data show acceptable results.
