The Need

In various scientific and engineering fields, the accurate measurement of time-dependent digital waveforms is paramount. From wireless communication systems and GPS to medical imaging like PET scans, precision timing is critical. Traditional methods utilizing separate time-to-digital converters (TDCs) and digital storage oscilloscopes (DSOs) have limitations, requiring specialized hardware and facing challenges in calibration and signal distortion.

The Technology

Introducing the Waveform-Capture-Device (WCD), a groundbreaking solution merging a 5 picosecond (ps)-resolution time-to-digital converter (TDC) with an ultra-fast digital oscilloscope (DO). Implemented on field-programmable gate arrays (FPGAs), the WCD offers unparalleled flexibility and precision. It captures complex GHz frequency waveforms at picosecond intervals, overcoming the shortcomings of traditional approaches.
