Abstract

A measuring device measures an input signal. The measuring device comprises at least two domains of measurement each for analyzing the signal in its corresponding manner, a selector for selecting a first domain of measurement or a second domain of measurement out of the at least two domains of measurement. A controller is in communication with the selector. The controller is configured to set a first bandwidth for the first domain of measurement and a second bandwidth for the second domain of measurement.

First claim

What is claimed is:

1. A measuring device for measuring a signal, the measuring device comprising:
at least two domains of measurement each for analyzing the signal in a corresponding manner;
a selector for selecting a first domain of measurement or a second domain of measurement out of the at least two domains of measurement;
a controller being in communication with the selector;
a protocol decoder configured to decode protocols; and
a display connected to an output of the protocol decoder, which is configured to display a time domain presentation of the signal in a first display area and a frequency spectrum of the signal or a presentation of a decoded protocol generated by the protocol decoder in a second display area; and
wherein the controller is connected to the protocol decoder,
wherein the controller is configured to set a first bandwidth for the first domain of measurement and a second bandwidth for the second domain of measurement, and
wherein the first bandwidth and the second bandwidth is each limited without allowing a user to access an entire bandwidth for each domain.

2. The measuring device according to claim 1 , wherein the first bandwidth is different from the second bandwidth.

3. The measuring device according to claim 1 , wherein each of the first domain of measurement and the second domain of measurement is selected from time, frequency or protocol decode.

4. The measuring device according to claim 1 , wherein each of the first bandwidth and the second bandwidth is available for analyzing the same signal on a single channel.

5. The measuring device according to claim 4 , wherein the single channel comprises a splitter configured to split the signal.

6. The measuring device according to claim 5 , wherein the splitter is further configured to provide an identical split of the signal to each of a plurality of filters.

7. The measuring device according to claim 6 , wherein at least one of the plurality of filters is a low pass filter.

8. The measuring device according to claim 1 , wherein at least one of the at least two domains of measurement comprises a fast fourier transform analysis.

9. The measuring device according to claim 1 , wherein the first bandwidth applies for an analysis in a time domain.

10. The measuring device according to claim 1 , wherein the second bandwidth applies for an analysis in a frequency domain.

11. A measuring method for measuring a signal, the measuring method comprising the steps of:
analyzing the signal according to each of at least two domains of measurement in a corresponding manner;
selecting a first domain of measurement or a second domain of measurement out of the at least two domains of measurement with the aid of a selector;
setting a first bandwidth for the first domain of measurement and a second bandwidth for the second domain of measurement with the aid of a controller being in communication with the selector;
decoding protocols with the aid of a protocol decoder which is connected to the controller; and
displaying, via a display connected to an output of the protocol decoder, a time domain presentation of the signal in a first display area or the display, and a frequency spectrum of the signal or a presentation of a decoded protocol generated by the protocol decoder in a second display area of the display;
wherein the first bandwidth and the second bandwidth is each limited without allowing a user to access an entire bandwidth for each domain.

12. The measuring method according to claim 11 , wherein the first bandwidth is different from the second bandwidth.

13. The measuring method according to claim 11 , further comprising the step of:
selecting each of the first domain of measurement and the second domain of measurement from time, frequency or protocol decode.

14. The measuring method according to claim 11 , wherein each of the first bandwidth and the second bandwidth is available for analyzing the same signal on a single channel.

15. The measuring method according to claim 14 , further comprising the step of:
splitting the signal on the single channel with the aid of a splitter comprised by the single channel.

16. The measuring method according to claim 15 , further comprising the step of:
providing an identical split of the signal to each of a plurality of filters with the aid of the splitter, wherein at least one of the plurality of filters is a low pass filter.

17. The measuring method according to claim 11 , wherein at least one of the at least two domains of measurement comprises a fast fourier transform analysis.

18. The measuring method according to claim 11 , wherein the first bandwidth applies for an analysis in a time domain.

19. The measuring method according to claim 11 , wherein the second bandwidth applies for an analysis in a frequency domain.
