Mirror facet single cone based minimum measurable rise time calibration method and system
By using a calibration method based on a mirror-like single cone, and combining time and frequency domain conditions, the probe rise time is directly determined as the minimum measurable rise time. This solves the problem of poor accuracy in mirror-like single cone measurements and enables high-precision probe calibration and universal application.

Abstract
本发明涉及脉冲场强计量技术领域，公开了基于镜面单锥的最小可测上升时间校准方法及系统，该方法包括：获取皮秒脉冲源所发出的皮秒快沿脉冲信号的第一上升时间、镜面单锥带宽所对应的第二上升时间、高带宽示波器带宽所对应的第三上升时间，以及高带宽示波器测量的探头上升时间；基于第一上升时间、第二上升时间、第三上升时间和探头上升时间判断是否满足预设条件，预设条件包括时域条件；若第一上升时间、第二上升时间、第三上升时间和探头上升时间满足时域条件，则判定探头上升时间为被测探头的最小可测上升时间。本发明提升了校准过程的抗干扰能力与结果的准确性，以确保被测探头应用的普适性。
