Abstract

A waveform capture device (WCD) is a flexible measurement system capable of recording complex digital signals on trillionth-of-a-second (ps) time scales. The WCD may be implemented via modular code on an off-the-shelf field-programmable gate-array (FPGA), and incorporates both time-to-digital converter (TDC) and digital storage oscilloscope (DSO) functionality. The device captures a waveform by taking snapshots of a signal as it propagates down an ultra-fast transmission line known as a carry chain (CC). It may be calibrated via a dynamic phase-shifting (DPS) method that requires substantially less data and resources than conventional techniques.
