Measurements
Conducted emissions testing focuses on emissions that are conducted along a power
line that are generated by the device under test (DUT). The transducer that is typically
used to couple the emissions of the power line to the signal analyzer is a line
impedance stabilization network (LISN).
The regulatory limits specify the maximum DUT emission energy, usually in dBμV,
detected by the LISN. The test range for these measurements is typically 150 kHz to 30
MHz, though some limits may start as low as 9 kHz, depending on the regulation.
