LSN016 is a 50Ω/50uH+5Ω V-type line impedance stabilization network that fully complies with the requirements of GB/T 6113.102-2008/CISPR 16-1-2:2006 and supports AC 220V/50Hz. It can provide a certain impedance to the EUT within the RF range of 9kHz to 30MHz and isolate the test circuit from the unwanted RF signals on the power supply circuit, thereby coupling the disturbance voltage to the measurement receiver.
