In this paper, we present results of profile of ion saturation current and its fluctuation statistics obtained from Langmuir probe measurements in the X-point region of ASDEX Upgrade. The machine was operated in L-mode and heated with electron cyclotron resonance heating(ECRH). Analysis of the time series show a significant difference between the probability distribution function and power spectral density, obtained at the low field side and high field side of the X-point.
