Measurement application device

Measurement application device comprising:

• a display device configured to display measured signals in a diagram comprising at least a first diagram axis and a second diagram axis;
• an input device configured to receive a first user-provided input marker, wherein the first user-provided input marker refers to a point in the diagram;
• and
• a computing device configured to calculate a difference value for each one of at least two of the diagram axes based in each case on a position of the first user-provided input marker in the diagram, and a position of a second input marker in the diagram,
• wherein the second input marker refers to a point in the diagram and is provided by a user as a second user-provided input marker, or wherein the second input marker refers to a point in the diagram and is automatically provided by the computing device as a second automatic input marker, and
• wherein the computing device is further configured to calculate a result based on the calculated difference values,
• wherein one or more of
• one of the diagram axes refers to time, and the other diagram axis refers to a frequency of the measured signals, and the computing device is configured to calculate a chirp rate of the measured signals as result by dividing the difference value referring to the frequency of the measured signals by the difference value referring to time;
• one of the diagram axis refers to time, and the other diagram axis refers to phase of the measured signals, and the computing device is configured to calculate a phase drift of the measured signals as result by dividing the difference value referring to the phase by the difference value referring to time;
• or
• one of the diagram axis refers to time, another diagram axis refers to the frequency of the measured signals, and another diagram axis refers to a power value of the measured signals, and the computing device is configured to calculate a chirp rate of the measured signals by dividing the difference value referring to the frequency of the measured signals by the difference value referring to time, and to output an information about at least one of intermodulation products and harmonics of the chirp rate based on the calculated chirp rate.
