Method for correcting frequency- and length-dependent line attenuation for tdr-measurements carried out on high-frequency cables

摘要

The method involves feeding pulses or pulse trains into the high frequency cable to be measured and determining the variation (aRn) with length of the attenuation for the cable, over the entire frequency range. The spectrum of the pulse or pulse train is determined. A correction factor is determined for correcting the attenuation characteristic (aRn) using the spectrum. The transformed values are corrected using the correction function to form corrected measurement values.
