Dear Pryor, As I know for EMC measurement uncertainty, below are the document can be used for reference. 1. New CISPR 16-4 2. "Lab 34" publised by UKAS. ( Free download from internet ) 3. A handy guide from Schaffner.com But all of them just mentioned about radiated emission up to 1GHz!!!! Probably you have read them. What I am interested is why you put absorbing material between the EUT and the Receiving anteanna, because for typical radiated emission measurement, we use semi-anechoic chamber ( no absorber on the ground plane between EUT and the antenna). We raised and lowered the antenna between 1-4m which is used for obtaining the maximum reading including the reflected path from the ground plane. There is absorber between EUT and antenna which is only in fully-anechoic chamber which is used for radiated immunity test. Regards,
Derek. Pryor McGinnis <[email protected]> 說： Does anyone have a guideline for calculating measurement of uncertainty above 1 GHz where absorbing material is placed on grouond plane between EUT and antenna per EN55011?
