当我测量空中（OTA）信号时，我的所有My Spectrum分析仪N9344C都会显示“过载”信息噪声基底也可能上升并隐藏感兴趣的信号。
即使OTA信号超出当前跨度，也会发生这种情况。 解决方案是使用外部带通滤波器将OTA信号限制到感兴趣的频带。 现在我想选择一个具有宽范围的带通填充器可调谐器（与N9344C相同，DC -20GHz）。 所以没有一个滤波器的范围DC - 20GHz。 请告诉我解决方案。 谢谢 以上来自于谷歌翻译 以下为原文 Hi all My Spectrum analyser N9344C display an “overload” message when I measure Over-the-Air (OTA) signal The noise floor may also rise and hide signals of interest. This can happen even if the OTA signal is outside of the current span. Solution is to use an external band pass filter to limit OTA signals to the band of interest. Now I want to choose one bandpass fillter tunable that had the wide range (the same to N9344C, DC -20GHz). so there aren't one filter that had range DC - 20GHz. Please advise solution for me. Thanks

嗨 - 解决方案是：A。调整频谱分析仪的衰减器值，或使用外部衰减器降低不需要的OTA信号。
B.根据您要测量的实际信号频率和带宽，选择较窄的频段选择器或使用多个选择器（带通滤波器）。 C.找到实际导致频谱分析仪过载的信号，并尝试使用适当的陷波滤波器来消除它对仪器的影响。 我希望这有帮助 - 以上来自于谷歌翻译 以下为原文 Hi - The solution would be: A. Adjust the attenuator value of the spectrum analyzer, or use an external attenuator to lower down the unwanted OTA signal. B. Choose a narrower band selector or to use multiple selectors (bandpass filters) according to the actual signal frequency and bandwidth which you want to measure. C. Find the signal which actually cause the overload of the spectrum analyzer, and try to use a appropriate notch filter to eliminate the impact of it to the instrument. I hope this helps - |

非常感谢，tabbott我选择解决方案B，但我想限制用于DC-20GHz频率范围的滤波器数量，这意味着我选择的多个选择器（带通滤波器）必须具有宽频率范围。
你能告诉我有最大频率范围的模型滤波器吗？ “B.根据您要测量的实际信号频率和带宽，选择较窄的频段选择器或使用多个选择器（带通滤波器）。” 以上来自于谷歌翻译 以下为原文 Thanks very much, tabbott I choose solution B, but I want to limit the number of filters to use for frequency range DC-20GHz, meaning the multiple selectors (bandpass filters) that i choose must a wide frequency range. Can you advise me model filter that had max frequency range. "B. Choose a narrower band selector or to use multiple selectors (bandpass filters) according to the actual signal frequency and bandwidth which you want to measure." |
