EMC test conducted emissions measurement query

Hello,

I want to measure emc conducted emissions for my electronic device. And the standards should be considered from CISPR-25, here are my questions:
How much frequency range should I consider for this Standard?
And How many LISN's do I require?
And How much should be the LISN frequency range for my measurement requirements?
Can I prepare LISN on my own on PCB by soldering components? How will be the schematic should be, can anyone send me the schematic diagram for LISN?
How much frequency range should be considered for the Absorber to attach in the chamber?

Thanks, Your help is appreciated, And These questions may require for others in this Forum too to go through easily on EMC tests.

Did you review previous threads about conducted emission measurements, e.g. https://www.edaboard.com/showthread.php?t=366369

Hello, Yes I've seen just now, thank you for the link. Can you please answer in short for my questions as the Standards are for CISPR-25.

Thanks

I'm not familiar with CISPR 25.

Ok, I will see if anyone says...
