Does any one know how to calculate power per carier
for say an antenna that has multiple carriers including
GSM, CDMA. The maximum composite power for the Downlink
is given.?
Thankyou

IMHO, some of HP spectrum analyzer has a capabilty
to measure a "relative power" per the mask size
of BW you tune.
For example, to measure a "relative"
composite power, you have to know the bw. Let's
say 200Mhz and SA measured as 20dBm while the actual
know power is -40dBm. And now you tune center freq
to the carrier you want measure and tune the mask
BW equal to the carrier BW. and let's say it is
5dBm. Then the difference is 15dB=20-5 so that the
carrier power is -55dBm = -40dBm -15...
At
least, this worked for me to measure power of carrier
recived from satellite.

Hi Daver, Who is the vendor? Lucent/Nortel/Nokia/Ericsson
?? There are pegs in the system which will give
you either Peak Power usage/carrier or Avg. power
usage per carrier - these pegs are on a sector/carrier
level...so you would have power/carrier/sector.
hope that helps! Let me know what technology
and the vendor, I may be able to give you the exact
peg. Cheers!
