Abstract: Embodiments of the present invention provide systems and methods for automatically performing TDR calibration to compensate for the time delay of a signal carried over a transmission environment (e.g., cable or other electrical path) used during DUT testing. A signal provider generates a signal along a signal path, and a circuit comprising a capacitor coupled to the signal provider and a diode coupled to the capacitor receives the signal periodically. A measurement unit coupled to the capacitor and the diode measures a voltage at the capacitor to determine a signal characteristic value of the signal along the signal path. The signal characteristic value is used to determine the electrical length (delay) of the transmission environment. TDR calibration is performed using the electrical length to compensate for the time delay/reflections over the transmission environment during testing.
