Abstract
In a Time Domain Reflectometry (TDR) measurement system including a measurement probe and an electronics assembly, a method for generating a time delay between transmit and receive pulses for capturing measurements in a given measurement cycle, comprising initiating first relatively slow and second relatively fast time-dependent non-linear ramped waveform functions associated with transmit and receive signals, respectively; and initiated at a time prior to initiation of the first time-dependent non-linear ramped waveform at a second time t0; comparing outputs of the first and second time dependent non-linear ramped waveform functions and activating a receive signal to measure a data point along the waveguide at a third time t1 when the outputs of the first and second time-dependent non-linear functions are equal; wherein the first and second time-dependent non-linear ramped functions are configured such that their waveform characteristics produces a time delay between time t0 and time t1 that is a linear function of time.
