Radiation properties of the source e.g. flux, flux density, brilliance, size and divergence of the photon beam, power, power density, angular distribution of power and flux on the axis of the undulator have been considered by theoretical formula and using SPECTRA code. At the circular polarization, the first harmonic covers the energies in the 100-1300 eV range and for the linear polarization energy ranges, 100-1000 eV and 1000-1500 eV, are provided by the first and third harmonics respectively. In the case of circular and linear polarization mode, maximum flux in the central cone for maximum undulator strength are 4.5 × 10¹⁶ (ph/s) at kX=ky=3.6 and 2.4 × 10¹⁶ (ph/s) at K=5.
