CH1 深度诊断报告

目的：在无法追加硬件验证和标签确认的晚上，从已有 2MSPS 信号里进一步判断高频风险更像目标动作、干扰、还是持续宽带底噪。

一、基线与风险组对比

A 类低频稳定基线文件数：30
A 类 RMS 中位数：25.966；峰值中位数：73.243；>250kHz 中位数：0.01%
C 类高频风险文件数：11
C 类 >250kHz 中，400k-1M 占比中位数：79.43%
C 类跨 1/10/100ms 高频稳定性中位数：83.65%
C 类 RMS 仅为 A 类中位数的 68.36%；峰值仅为 A 类中位数的 26.46%

二、诊断类型计数

{
  "低频稳定样本，可作为500ksps正向证据": 30,
  "持续宽带高频底噪/非目标状态嫌疑高": 11,
  "过渡/边界样本，建议作为复核补充": 7
}
