Electro-Metrics前置放大器 可调滤波器EM-7842

品牌：Electro-Metrics

型号：EM-7842

? ? ? ?Electro-Metrics EM-7842可调谐陷波滤波器网络是一种可调谐窄带抑制滤波器，工作频率从15 MHz到100 MHz。当一个选定频率需要高抑制（衰减）而其他频率需要低衰减时，就使用它。EM-7842的高功率额定值允许在高功率变送器上进行测量，前提是电压输入电平经过仔细调节。

? ? ? ?该EM-7842涵盖了从15兆赫至100兆赫在两（2）个频段使用可变电容器和电阻器加上两（2）个可互换的固定电感调谐线圈。不用时，调谐线圈存放在单独的手提箱中。选择的调谐线圈通过装置的可拆卸顶盖插入EM-7842的内部电路。
