Research on the traceability of pulse waveform parameters in NIM

This paper describes some research on the traceability of pulse waveform parameters in NIM. The tracing method of high-precision pulse amplitude is researched based on digital sampling and algorithm processing. The tracing method of transient response of sampling oscilloscope is researched based on NTN calibration technology, and a primary standard of pulse waveform parameters is established. The tracing method of transition duration of ultrafast pulse made by photodetector is researched based on EOS technology. NIM participated in the international comparison of waveform and submitted the data.
