The progress in the turbulence diagnostic simulator is presented by showing an example ot data analyses with drift-interchange mode turbulence in helical plasmas. The multi-point spatial and temporal correlation analyses reveal the characteristic structures formed in the magnetized plasmas. The modules simulating experimental measurements subtract time series of fluctuations from the stored data, taking account of a finite spatial resolution of each instrument. The numerical diagnostics provide analyses as same in the experiments, which aid the development of the data analysis technique to deepen our physical understandings.
