b.The RBW method measures the power in the adjacent channels within the defined resolution band- width. The noise bandwidth of the RBW filter is nominally 1.055 times the 3.01 dB bandwidth. There- fore, the RBW method will nominally read 0.23 dB higher adjacent channel power than would a measurement using the integration bandwidth method, because the noise bandwidth of the integration bandwidth measurement is equal to that integration bandwidth. For cdma2000 ACP measurements using the RBW method, the main channel is measured in a 3 MHz RBW, which does not respond to all the power in the carrier. Therefore, the carrier power is compensated by the expected under-response of

the filter to a full width signal, of 0.15 dB. But the adjacent channel power is not compensated for the noise bandwidth effect.

The reason the adjacent channel is not compensated is subtle. The RBW method of measuring ACP is very similar to the preferred method of making measurements for compliance with FCC requirements, the source of the specifications for the cdma2000 Spur Close specifications. ACP is a spot measure- ment of Spur Close, and thus is best done with the RBW method, even though the results will disagree by 0.23 dB from the measurement made with a rectangular pass band.
