Cable Test or Time Domain Reflectometer (TDR) mode is intended to identify potential coaxial
cable faults that could disrupt signal transmission. Unlike native TDR test equipment, the
method of measurement in the SARK-110 is based on the theory of Frequency Domain
Reflectometry (FDR).
The analyzer makes swept reflection measurements over the entire frequency range and
mathematically transforms the gathered data to Time Domain using an inverse Fourier
transform. As a result, the step and impulse responses are plotted on the display, providing
