    TETRA Release 2 Introduction 2 Introduction The R&S SMx/AMU-K68 enables you to to generate signals in accordance with the standard Terrestrial Trunked Radio Release 2 (TETRA2). To playback a signal from a waveform file created by the simulation software R&S WinIQSIM2, the corresponding R&S WinIQSIM2 digital standard option must be installed.
