RFS-E 03型探头底部的电极大小约为 4 x 4 mm。 如此可以定位电缆、IC引脚或更小组件中的电场。
The RFS-E 03 is a passive near-field scanner probe. For measurements the E-field probe is positioned above the components or areas of the PC board. The near-field probe has a sheath current attenuation and is electrically shielded. It can be connected to a spectrum analyzer or an oscilloscope with a 50 Ω input. The E-field probe does not have a 50 Ω terminating resistor internally.
