Line Impedance Stabilization Networks

[CLAYMORE]

Looking for information on how to verify the performance of Line Impedance Stabilization Networks. I've seen reports from labs with their performance data, but I am unable to find any documentation that specifies how the tests are conducted.

CISPR 16-1-2 tells you the basics for the calibration.

Thank you,

Are there free copies available that you are aware of?

No that would have to be purchased. They watermark them now so can't send it to you.

Can you tell me what type of standards CISPR 16-1-2 calls out for?

I see maybe 10 of the Ficher P/N FCC-LISN-DO-160 per year. I'd like to be able to advise on buying the procedure.

The standards required will be all Agilent items, 4395A, 87511A and 85032B. Also you will need a grounding bar into earth ground along with ground planes (sheet metal) on both the floor and benchtop.
Also instead of the CISPR document being your guideline you will have to purchase the RTCA DO-160 requirement instead.
The main issue you will have is that you will need to manufacture your own connectors as FCC will not sell them and they do not offer any calibration support.

Thanks, I can see that it will likely make no sense to buy those standards in order to certify 10 units a year so we'll probably keep on outsourcing the LISNs to Fischer.
