ABSTRACT:
The invention concerns a method and a device for phase calculation from attenuation values using a Hilbert transform for reflectometric measurements in the frequency domain. The invention is characterized in that the measuring system comprises a signal source for a measurement signal, a coupling element connected to the signal source, and an object to be measured connected to the coupling element. The part of the measurement signal reflected by the object to be measured is uncoupled via the coupling element and measured at a collector. The invention is further characterized in that an attenuator is mounted in the signal path, between the coupling element and the object to be measured. The attenuator can also be comprised in the coupling element.
