Ground Current With and Without Filter *

* Measurement Tool: NOISE HiLOGGER 3145-20, CLAMP ON NOISE SENSOR 9754

* The 3145-20 separates noise between 10kHz and 100MHz into seven frequency bands, and displays the noise current level of each band as one bar in a bar graph, which is refreshed every 100ms.

* A frequency band of up to less than 1MHz is Conductivity Frequency Range flowing through the cable. However, a frequency band of more than 1MHz is Radiation Frequency Range, which is propagating space. Therefore, increase or decrease of the left hand graph on 3145E screen@indicates attenuation performance.
