有源MFA(1 MHz - 6 GHz)

该微型探头可以精确测量电路布局、最小的SMD-元器件(0603-0201)以及平面电路板的IC引脚等的高频磁场。这种探头是有源探头,采用电屏蔽设计,具有外皮电流衰减性能。借助校正曲线可以将探头的输出电压换算为对应的磁场或者导线的电流。该近场探头通过BT 706型偏置器连接到频谱分析仪或者示波器的50Ω输入端。通过标准配置中包含的外接电源适配器和偏置器,可以为内置在探头中的前置放大器供电。

The MFA near-field probes are not suitable for RF coupling (injection)!

The MFA microprobes are active near-field probes, i.e. they have an integrated pre-amplifier. With a measurement resolution range up to 300 µm, these probes are particularly suitable for measuring RF magnetic fields in very small areas on the assembly, e.g. IC pins, the thinnest conducting paths, or smallest SMD components (0603-0201).
