Abstract
A power meter comprises at least two measurement paths and distribution device. A first measurement path contains at least one pre-amplifier and a first detector. A second measurement path contains at least one direct connection and a second detector. An additional third path alternative to or optional to the second path contains at least one attenuation element and a second or respectively third detector. The distribution device distributes a test signal to the measurement paths.
Claims10
A power meter comprising:
- a first measurement path that contains at least one pre-amplifier and a first detector;
- and
- a second measurement path that contains at least one direct connection and a second detector;
- and/or a third measurement path that contains at least one attenuation element and a second or respectively third detector;
- a distribution device adapted to activate one or more measurement paths dependent upon the power of test signals and distribute the test signals to the one or more activated measurement paths;
- and
- a digital signal processing device adapted to process the test signals of all activated measurement paths in a time-parallel manner so that power measurement values of the different measurement paths are combined to form a common power-measurement value.
