Data from a single spacecraft wave interferometer on Viking is used to illustrate the potential capabilities of the Electric Field Wave (EFW) experiment on Cluster. The EFW experiment for Cluster consists of four probes mounted on 50 m long booms. The instrument is capable of measuring density and/or electric field waveforms with up to 9000 samples/s per probe in many different operation modes. One useful combination is to measure density fluctuations on two probes and to use the other two probes for electric field measurements. By measuring the time difference of a wave front arrival at two probes, the velocity of plasma structures can be determined. The high sampling frequency will make it possible to resolve the plasma fronts/wave velocities of up to 900 km/s by a single spacecraft interferometer. Multispacecraft interferometry with base lengths of 300 to 6000 km will increase significantly the capabilities of the instrument and will make it possible to measure group velocities of fast magnetosonic/Alfven waves, to resolve the wave propagation directions and to determine the spatial extent of plasma structures.
