ABSTRACT
Time-domain reflectometry (TDR) is used to characterize interconnections in the time domain. The setup essentially consists of a time domain step generator and a digital sampling oscilloscope (Figure 17.1) [1]. The generator produces a positive-going step signal with a well-defined rise time. The step is applied to the device under test. The reflected and the transmitted signals are shown on the oscilloscope. Measuring the reflected signal is called TDR; the transmitted signal is measured using the time-domain transmission (TDT) option.
