In this paper, we present experimental results and appropriate models to explain the effects that were found to be caused by impedance mismatches of electronic components and dispersion effects in coaxial cables of gravimeters. In Křen et al (2016 Metrologia 53 27-40) we found that for an FG 5 gravimeter, even a few meter long coaxial cable used for transmission of fringe signal causes systematic features in residuals and errors at the level of 1-2 µGal. The systematic effects of absolute gravimeters have to be investigated to fully utilize their capabilities in metrology and geosciences.
