Any EN 300-220 European standard guru out there ?
I have some difficulties to deduce the maximum phase noise profile of a transmitter from this standard in the case of a very narrow bandwidth transmitter (say 10KHz bandwidth, operating in a non-standard VHF frequency band) :
- Standard gives a limitation of the transmitted power in the adjacent channels (10µW integrated over each adjacent channel). Fine
- Standard gives a limitation for the spurious emissions (-36/-54dBm under1GHz with 100KHz spectrum analyzer bandwidth depending on the frequency). Fine.
But what is the maximum noise or side modulation levels say 2, 3 or 10 channels away from the carrier ? My first assumption was that the "spurious" specification was applicable, but with a 100KHz resolution bandwidth I would be measuring the carrier power if I do the measurement even 5 channels away from the carrier...
Any help welcome...
Friendly yours, Robert
