True performance of a TDR (Time Domain Reflectometer) in terms of digital bandwith is evaluated using intrinsic worst case eye diagrams related to incident and reflected TSR steps. A first analysis related to the historical Tektronix 7S12 TDR is presented. The eye diagrams are calculated in the DW (Digital Wave) environment using both DWS (simulator) and DWV (viewer) programs. The digitizing of TDR waveforms is performed using the Get Data Digitizer freeware program.THe present application has been carried out within the SWAN (Simulation by Wave Analysis) project. This methodology doesn't require frequency domain analysis.
