Abstract

An apparatus for measuring radio frequency power is provided. The apparatus comprises at least one interface, at least two measurement paths, and a processor. In this context, at least two of the at least two measurement paths are connected to a single interface, whereas the at least two measurement paths are connected to the processor in order to provide measurement data for the processor. In addition to this, the processor is configured to select one of the at least two measurement paths for producing a measuring result on the basis of at least one environmental sensor value from at least one environmental sensor and/or on the basis of at least one user input.

First claim

What is claimed is:

1. An apparatus for measuring radio frequency power, the apparatus comprising:
at least one interface,
at least two measurement paths, and
a processor,
wherein the at least two measurement paths are connected to a single interface,
wherein the at least two measurement paths are connected to the processor in order to provide measurement data for the processor, and
wherein the processor is configured to select one of the at least two measurement paths for producing a measuring result on the basis of at least one environmental sensor value from at least one environmental sensor or on the basis of at least one user input.

2. The apparatus according to claim 1 ,
wherein the at least one interface comprises a connector or an antenna.

3. The apparatus according to claim 1 ,
wherein a connection between the at least two measurement paths and the single interface is switchable by a radio frequency switch or fixed by a splitter.

4. The apparatus according to claim 1 ,
wherein the at least one environmental sensor value comprises data with respect to at least one of temperature, pressure, humidity, vibration, shock, or a combination thereof.

5. The apparatus according to claim 1 ,
wherein the environmental sensor comprises a temperature sensor, a pressure sensor, a humidity sensor, a vibration sensor, a shock sensor, or a combination thereof.

6. The apparatus according to claim 1 ,
wherein the at least two measurement paths having different measurement paths and comprise different power detectors.

7. The apparatus according to claim 6 ,
wherein the different power detectors are configured for different temperature areas.

8. The apparatus according to claim 7 ,
wherein the different power detectors are configured for different temperature areas on the basis of different detector diodes with different diode designs in the respective detectors.

9. The apparatus according to claim 8 ,
wherein the different diodes arranged in different measurement paths having different temperature characteristics.

10. A method for measuring radio frequency power, the method comprising the steps of:
connecting at least two measurement paths to a single interface,
connecting the at least two measurement paths to a processor in order to provide measurement data for the processor, and
selecting one of the at least two measurement paths for producing a measuring result on the basis of at least one environmental sensor value from at least one environmental sensor or on the basis of at least one user input with the aid of the processor.

11. The method according to claim 10 ,
wherein the single interface comprises a connector or an antenna.

12. The method according to claim 10 ,
wherein a connection between the at least two measurement paths and the single interface is switchable by a radio frequency switch or fixed by a splitter.

13. The method according to claim 10 ,
wherein the at least one environmental sensor value comprises data with respect to at least one of temperature, pressure, humidity, vibration, shock, or a combination thereof.

14. The method according to claim 10 ,
wherein the environmental sensor comprises a temperature sensor, a pressure sensor, a humidity sensor, a vibration sensor, a shock sensor, or a combination thereof.

15. The method according to claim 10 ,
wherein the at least two measurement paths having different measurement paths and comprise different power detectors.

16. The method according to claim 15 ,
wherein the method further comprises the step of configuring the different power detectors for different temperature areas.

17. The method according to claim 16 ,
wherein the method further comprises the step of configuring the different power detectors for different temperature areas on the basis of different diodes with different diode designs in the respective detectors.

18. The method according to claim 17 ,
wherein the method further comprises the step of selecting diodes with different temperature characteristics for the different measurement paths.
