If necessary, adjust the [SPAN] key, and then you can see the complete filtering characteristics of the filter on the display.
—Press 【Marker】key to move the cursor to -3dB, then you can measure the 3dB bandwidth of the filter.
If you want to take a closer look at the filter characteristics, you can choose the ordinate scale of 1dB/grid.

4.1 Near-field probes

Using a near-field probe with a receiver can directly measure the frequency and amplitude of the interference signal, which is very effective in
finding electric and magnetic field interference. Compared with similar probes, the Baluelec near-field probe has high gain and small volume, and
can perform quantitative measurements.
