The present invention relates to an enhanced control of a measurement device displaying a signal waveform of a measurement signal. For this purpose, the waveform of the measurement signal is displayed on a touch-screen. The touch-screen receives multi-digit touch gestures comprising at least two touch gestures. The touch gestures of the multi-digit touch gesture are analyzed in order to determine simultaneously an operation and a range of the measurement signal on which the determined operation has to be applied. In this way, the control of the measurement device can be simplified.
