CH1 广州清诚决策评估数字化报告

主评估窗口采用专家基准 1ms FFT。统计对象为 48 个现场 TXT 文件的 CH1 全量数据。比例均为频谱能量占比，不是时域电压占比。

一、总体指标

总文件数：48
低频稳定 A 类：30 个，占 62.50%
过渡/混合 B 类：7 个，占 14.58%
高频风险 C 类：11 个，占 22.92%
125kHz 内能量 >=90% 的文件：31 个，占 64.58%
250kHz 以上能量 <1% 的文件：30 个，占 62.50%
250kHz 以上能量 >=20% 的文件：11 个，占 22.92%
250kHz 以上能量 >=40% 的文件：6 个，占 12.50%

二、分型定义

A 类：>250kHz <1% 且 125kHz 以外 <5%，低频稳定，支持 500ksps。
B 类：不满足 A，也未达到 C，过渡/混合，需复核。
C 类：>250kHz >=20%，高频风险，500ksps 可能混叠或漏掉关键信息。

七、结论

CH1 对 500ksps 的支持不是“全量无条件通过”，而是“多数文件强支持 + 少数高频风险文件需要现场解释”。今晚无法确认硬件和复采时，最关键的动作是明天优先复核 C 类文件是否属于目标碰/敲/切/挤。
