Abstract

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.

First claim

The invention claimed is:

1. A measurement apparatus for analyzing a measurement signal, wherein the measurement apparatus includes an oscilloscope comprising:
an input port, adapted to receive a measurement signal;
a touch-screen, adapted to display a waveform of the received measurement signal and to receive a multi-digit touch gesture, the multi-digit touch gesture comprising at least a first touch gesture and a second touch gesture,
wherein the first touch gesture and the second touch gesture relate to lines which are parallel to an x-axis or y-axis of the touch-screen; and
a measurement signal processing device, adapted to determine an operation and a range of the measurement signal based on the received multi-digit touch gesture, and to perform a processing of the measurement signal based on the determined operation and the determined range,
wherein the measurement signal processing device is configured to identify a characteristic parameter in the determined range according to said received multi-digit touch gesture, and to determine said operation and range of the measurement signal based on the identified characteristic parameter.

2. The measurement apparatus of claim 1 , wherein the touch-screen is adapted to simultaneously receive the first touch gesture and the second touch gesture.

3. The measurement apparatus of claim 1 , wherein the touch-screen is adapted to receive the first touch gesture and the second touch gesture subsequently.

4. The measurement apparatus of claim 1 , wherein the measurement signal processing device is adapted to determine whether the determined range relates either to an x-axis or a y-axis.

5. The measurement apparatus of claim 1 , wherein the determined range is smaller than the range of the waveform currently displayed on the touch-screen.

6. The measurement apparatus of claim 1 , comprising a configuration device, adapted to specify a predetermined signal processing for a specific multi-digit gesture.

7. The measurement apparatus of claim 1 , wherein the determined operation comprises displaying a context menu providing multiple options.

8. The measurement apparatus of claim 1 , wherein the measurement signal processing device is configured to perform at least one of zooming the waveform to the determined range, determining a rising or falling time or determining a duty cycle.

9. The measurement apparatus of claim 8 , wherein the signal processing device is configured to perform identifying a minimum or a maximum value.

10. The measurement apparatus of claim 1 , wherein the touch-screen is adapted to display a track of the received multi-digit touch gesture on the touch-screen.

11. The measurement apparatus of claim 1 , wherein the touch-screen is adapted to display an indication associated to the determined operation or the determined range.

12. A method for analyzing a measurement signal by an oscilloscope, the method comprising the steps of:
receiving a measurement signal;
displaying a waveform of the received measurement signal on a touch-screen;
receiving a multi-digit touch gesture, the multi-digit touch gesture comprising at least a first touch gesture and a second touch gesture, wherein the first touch gesture and the second touch gesture relate to lines which are parallel to an x-axis or y-axis of the touch-screen;
determining an operation and a range of the measurement signal based on the received multi-digit touch gesture; and
processing of the measurement signal based on the determined operation and the determined range, wherein the processing comprises identify a characteristic parameter in the determined range according to said received multi-digit touch gesture,
wherein said operation and range of the measurement signal are determined based on the identified characteristic parameter.

13. An oscilloscope, comprising:
an input port, adapted to receive a measurement signal;
a touch-screen, adapted to display a waveform of the received measurement signal and to receive a multi-digit touch gesture, the multi-digit touch gesture comprising at least a first touch gesture and a second touch gesture, wherein the first touch gesture and the second touch gesture relate to lines which are parallel an x-axis or y-axis of the touch-screen; and
a measurement signal processing device, adapted to determine an operation and a range of the measurement signal based on the received multi-digit touch gesture, and to perform a processing of the measurement signal based on the determined operation and the determined range,
wherein the measurement signal processing device is configured to identify a characteristic parameter in the determined range according to said received multi-digit touch gesture, and to determine said operation and range of the measurement signal based on the identified characteristic parameter.
