EN300220 and phase noise
 

Hi all,

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 under
1GHz 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
