I’m struggling, too. It would appear as though you cannot correct for phase angle variations in your LISN; it only affects your measurement uncertainty calculations. Phase angle would not be factored in to your test results or your correction factors. If your LISN is bad or going bad, it should show up during the attenuation and impedance test. Am I understanding this correctly?

I'm trying, but failing to understand why phase would be important for a LISN or for any other transducer used during EMC evaluation. Don't EMC receivers report received signals as a scalar value? _______________________________________ _____________________________________________ Ralph McDiarmid | Schneider Electric | Renewable Energies Business | CANADA | Regulatory Engineer From: John Woodgate <[email protected]> To: [email protected] List-Post: [email protected] List-Post: [email protected] List-Post: [email protected] Date: 08/19/2010 09:34 AM Subject: Re: [PSES] LISN phase characteristic? ________________________________ In message <of480480bf.64652f9c-on88257784.00585b52-88257784.0058c...@slpower.com>, dated Thu, 19 Aug 2010, [email protected] writes: >In a recent posting, someone mentioned that CISPR/A may consider adding >phase characteristics (?) to LISN specifications.
