Hi,
Page 2 of this...
https://www.tekbox.com/product/TBL0550-1_Manual.pdf (https://www.tekbox.com/product/TBL0550-1_Manual.pdf)
..shows a 5uH LISN with a 5uH inductance.
But 07:25 of this video, shows the 5uH LISN schematic with some 470R resistors connected across the inductance..

Do you know which one is used by the standards bodys?
Also, what is the output filter of the power supply used at the EMC labs, upstream of the LISN? (pse see attached).....its output CLC filter affects the peak of the ring-up voltage when the DUT is suddenly switched ON....there is a danger of overvoltaging something at the DUT.
