ABSTRACT:
A method and apparatus are provided for implementing automatic-calibration of a Time Domain Reflectometer (TDR) probing apparatus. A calibration procedure is performed automatically each time a TDR probe is moved from a device under test (DUT). A current calibration TDR waveform is obtained and compared with a reference calibration TDR waveform, checking for deviations between the current and reference measurements. If a deviation is detected, then the user is notified and calibration is failed.
