检测和消除电磁干扰

适用于罗德与施瓦茨信号与频谱分析仪的 EMI 预一致性应用(K54 选件)扩展了产品开发过程中的 EMI 分析,并有助于构建平稳顺利的产品认证流程。典型应用领域包括商业、汽车电子、航空电子和军事产品开发(涵盖 CISPR、EN、FCC、DO-160 和 MIL-STD-461 标准)。

特性和优点

提供确切结果

  • 检波器符合 CISPR 16-1-1 标准:峰值、准峰值、CISPR 平均值、RMS 平均值
  • 6 dB 带宽符合 CISPR 16-1-1 标准:200 Hz、9 KHz、120 kHz 和 1 MHz
  • 6 dB 带宽符合 MIL-STD-461 和 DO-160 标准:10 Hz、100 Hz、1 kHz、10 kHz、100 kHz 和 1 MHz
  • 提供一个或多个转换因子选项以补偿天线因子或电缆衰减等
  • 限值线:根据最新的通用 EMI 标准,限值线超过 170 条

选择两个转换因子(线路阻抗稳定网络和相关线缆)。

测量自动化

自动化测试序列实现可重复的快速测量

  • 预测试:使用一个或多个快速检波器(例如峰值或平均值检波器)扫描设置的频率范围 
  • 识别临界频率:自动检测峰值和限值偏差,并以表格方式展示发现的频率  
  • 针对确定频率进行最终测量:使用需要较长测量时间的检波器(例如准峰值检波器)自动进行最终测量,并根据设置的限值线进行最终评估

深度信号分析

  • 最多 200 001 个扫描点,即使在大频跨/小测量带宽条件下也能实现出色的频率分辨率
  • 即使频率范围较宽,也可使用对数频率刻度进行深度低频分析
  • 零跨度测量,可使用标准检波器和 CISPR 检波器分析选定频率下随时间变化的信号行为
  • 具有音频输出的调幅和调频解调可识别环境干扰
