We have investigated various spectral parameters of Novosibirsk terahertz free electron laser (FEL) in different regimes by Bruker vacuum Fourier spectrometer IFS-66v. In addition to routine wavelength measurement and calibration we studied also radiation of harmonics [1] and detailed form of FEL spectrums. Such interesting phenomena as sideband instability [2] and two wavelength generation have been demonstrated very distinctly in our FEL.
