Dear colleagues, My subject of interest is the statistical rule explain in chapter 9.2 of EN55022 (also called the 80/80). Reading the standard, I don't know on which value I have to apply the rule. In fact, I usually apply the rule on each suspect frequency (about 5 by product) and I compare the calculated LEVEL to the Limit, in dBµV.
One of my customer is asking me to make this calculation on the MARGIN. For each product, I have to take the worst margin, and I make the calculation for the x products I have. The calcul gives a result which has to be compare to 0 (zero). The resulting margin has to be less than 0. How do you perform this calculation ? On which value do you perform it (margin, level, azimuth, height of antenna, ...) ? What are your own experience with your products or your customer ? In advance, I thank you a lot for your answer, which, I'm sure, will be of great value (80/80 calculation, of course !!)
