Turbulence spectra of density fluctuations measured with Doppler Reflectometry at the FT‐2 tokamak are com‐pared to full f nonlinear gyrokinetic simulations by means of a synthetic Doppler reflectometry diagnostic. The experimental and synthetic power spectrum of the Doppler reflectometer show good agreements in both the Doppler shift as well as the width of the power spectrum, indicating comparable rotation and spreading of the turbulence. The averaged radial electric field is shown to closely folllow the neoclasical Hazeltine Hinton value and Geodesic Acoustic mode are clearly identified by the width of the spectra (© 2010 WILEY‐VCH Verlag GmbH & Co.
