HIOKI – 3145-20

The impedance of an earth line is proportional to its length and frequency. When noise current flows in an earth line, the resulting noise voltage may swing the potential of an electronic device to cause noise interference.

The impedance of an earth line is proportional to its length and frequency. When noise current flows in an earth line, the resulting noise voltage may swing the potential of an electronic device to cause noise interference. Using the Hioki Noise HiLogger 3145-20 with the Clamp-On Noise Sensor 9754, the noise current level and frequency of the earth line can be measured simply, without direct contact.

The Hioki 3145-20 separates noise between 10 kHz and 100 MHz 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. Just clamp around a signal line and start measuring immediately.
