Abstract
An apparatus for measuring radio frequency power is described that comprises at least one measurement path for small bandwidth and at least one measurement path for wide bandwidth. Further, the apparatus has an analysis and measurement unit connected with the at least two measurement paths. The analysis and measurement unit is configured to process the at least one small bandwidth signal and the at least one wide bandwidth signal. Further, a method of analyzing a radio frequency signal is described.
Claims18
An apparatus for measuring radio frequency power, comprising:
- a housing;
- at least two measurement paths, said at least two measurement paths having at least one measurement path for small bandwidth via which at least one small bandwidth signal is processed and at least one measurement path for wide bandwidth via which at least one wide bandwidth signal is processed, said at least two measurements paths processing different signals with regard to the bandwidth;
- and
- an analysis and measurement unit connected with said at least two measurement paths, said analysis and measurement unit being configured to measure the power of said at least one small bandwidth signal and said at least one wide bandwidth signal,
- wherein said housing houses said at least two different measurement paths, and
- wherein said analysis and measurement unit is configured to indicate at least one of a too high power, a wrong attenuator setting or a wrong frequency range for said at least one measurement path for small bandwidth by comparing at least one predefined threshold value with an absolute power of said at least one small bandwidth signal and/or said at least one wide bandwidth signal.
A method of analyzing a radio frequency signal, with the following steps:
- receiving a radio frequency signal via a single apparatus having a housing that houses two different measurement paths;
- processing said radio frequency signal received via the single apparatus so as to obtain at least one small bandwidth signal and at least one wide bandwidth signal since said at least two measurements paths process different signals with regard to the bandwidth;
- and
- measuring the power of at least one of said at least one small bandwidth signal and said at least one wide bandwidth signal by using the single apparatus,
- wherein at least one of a too high power, a wrong attenuator setting or a wrong frequency range for said at least one measurement path for small bandwidth is indicated by comparing at least one predefined threshold value with an absolute power of said at least one small bandwidth signal and/or said at least one wide bandwidth signal.
