Frequency domain measurements for use in network analyzers, etc., whereby Hilbert transformations are carried out on attenuation values to provide more accurate phase calculations from reflectometric measurements

摘要

Method for phase calculation from attenuation values using a Hilbert transform for reflectometric measurements in the frequency domain. The method uses a measurement system with a measurement signal source and a coupling element between an object being measured and the source. The part of the measurement signal reflected by the object to be measured is uncoupled via the coupling element and measured at a collector. An Independent claim is made for a device for phase calculation that has a coupling member (3) linking a measurement object (5) to a signal source (1). An attenuator (4) is connected within the signal path between measurement object and signal source or integrated within the coupling member.
