Abstract

An instrument is described which comprises an input for receiving a signal, a data processing unit for analyzing said received signal and providing data to be displayed, and a touch enabled display screen for displaying said data to be displayed and receiving commands directed to said data processing unit. Said commands comprise commands that determine how said data is displayed on the touch enabled display screen and commands that determine operations that are performed by said instrument and/or said data processing unit. Said commands are specified by control gestures on said touch enabled display screen. Said control gestures are unambiguously related to certain commands. Said data processing unit recognizes said control gestures wherein said data processing unit is configured to determine a corresponding command specified by said detected control gesture and to process said determined command. Said instrument is a test instrument for measuring and/or analyzing said received signal.
