> Dear All, > I will appreciate your opinions concerning the following: > 1. R&TTE Radio standards include for products having an integral > antenna, a radiated power/ spurious test (EIRP), based on the substitution > antenna method. > 2. The final test result is: > signal generator level + overall correction factors > The overall correction factor consists mainly of the coaxial > cable loss and substitution antenna gain. > 3. According to ETSI TR 100027, (page 89), the overall correction > factor consists of various losses with a plus (+) sign and gain of > substitution antenna with a minus (-) sign. > 4. According to my understanding, the EIRP test result is the signal > generator power delivered to an isotropic antenna port. > Therefore the signs should be reversed: > e.g.: > a. The coaxial cable loss redices the level > delivered to the substitution antenna port (minus (-) sign). > b. With a substitution antenna having gain > (Horn Antenna), less signal generator power (plus (+) sign) will be > required. > 5.
