Electro-Metrics前置放大器 可調(diào)濾波器EM-7842
品牌：Electro-Metrics
型號(hào)：EM-7842
Electro-Metrics EM-7842可調(diào)諧陷波濾波器網(wǎng)絡(luò)是一種可調(diào)諧窄帶抑制濾波器，工作頻率從15 MHz到100 MHz。當(dāng)一個(gè)選定頻率需要高抑制（衰減）而其他頻率需要低衰減時(shí)，就使用它。EM-7842的高功率額定值允許在高功率變送器上進(jìn)行測(cè)量，前提是電壓輸入電平經(jīng)過(guò)仔細(xì)調(diào)節(jié)。
該EM-7842涵蓋了從15兆赫至100兆赫在兩（2）個(gè)頻段使用可變電容器和電阻器加上兩（2）個(gè)可互換的固定電感調(diào)諧線圈。不用時(shí)，調(diào)諧線圈存放在單獨(dú)的手提箱中。選擇的調(diào)諧線圈通過(guò)裝置的可拆卸頂蓋插入EM-7842的內(nèi)部電路。
