The properties of the turbulent fluctuations in the different phases of the ISM are of eminent interest for many branches of astrophysical research. The access to these fluctuation via observational means, however, is limited. Additionally, the connection of the observational results to the actual plasma state is ambiguous in most cases. This can best be investigated by way of numerical simulations. For this we applied the known observational methods to the results of such a simulation.
In this context we will present most recent results obtained using a numerical model for the warm interstellar medium. From these simulations we extracted many of the known observational measures. We will show that these observations have to be interpreted with great care even for the rather quiet state of the warm interstellar medium.
