Title: Takehiko Kawauchi: Innovator in Waveform Measurement Technology

Introduction

Takehiko Kawauchi is a prominent inventor based in Atsugi, Japan. He has made significant contributions to the field of waveform measurement technology, holding a total of four patents. His innovative work has advanced the capabilities of measurement apparatuses, enhancing their functionality and efficiency.

Latest Patents

Kawauchi's latest patents include a waveform measuring apparatus designed to provide a pretrigger function easily. This apparatus features a dummy readout circuit that applies first read signals of the same period as sampling signals to a read clock terminal of a FIFO memory. This design allows for concurrent reading from and writing to the FIFO memory while maintaining a difference between the write pointer value and the read pointer value equal to a predetermined prepoint value. When a trigger signal is generated, digital data are written into the FIFO memory until the write pointer value catches up with the read pointer value, enabling effective data management.

Another notable patent is a waveform display apparatus that facilitates high-definition waveform realization. This measurement unit sweeps frequencies within a predetermined range to obtain waveform data, which is then displayed on a display device. The control unit manages the measurement process, allowing for the enlargement or reduction of waveform data based on changing measurement frequency conditions. This innovation significantly enhances the observation quality of waveforms.
