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

摘要

The invention relates to a method for correcting the frequency and length-dependent line loss in TDR measurements on high-frequency cables. The invention is based on the problem that results from reflection factor measurements due to the cable own frequency and length-dependent attenuation have significant errors, which limit their significance.; The invention is based on that a length-dependent correction function is calculated for each to be measured cable type under joint use of specified by the manufacturer attenuation values ​​and recording the spectrum of a high-pass filtered measurement pulse sequence, the present in the time domain measurements of the reflection factor to be corrected with the then being physically located give correct values.
