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 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; and a controller being in communication with the selector; and 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.

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 the 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; and 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.

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.
