EV-DO ACP

EV-DO ACP Carrier Channels

Carrier channels are the channels transmitted by the user equipment when the measurement is performed. For ACP measurements, you can configure multiple carrier channels by specifying their carrier offsets with respect to the configured analyzer center frequency. ACP measurements measure the individual channel power for each configured carrier channel as well as the total transmitted carrier power of the mobile terminal. The total transmitted carrier power is the sum of the powers of the carrier channels. The total transmitted carrier power is used as the power reference for the offset channel measurements.

EV-DO ACP Offset Channels

ACP measurements measure the absolute and relative power for a specific set of offset channels adjacent to the carrier channels. ACP measurements use predefined configurations derived from the spectral emission limits defined in the 3GPP standard.

Single Carrier Offset Channels

Single carrier EV-DO ACP measurements perform offset power measurements of 30 kHz integration bandwidth at specific, band class-dependent offset frequencies where offset frequency refers to the difference between the carrier center frequency and the closer measurement edge frequency, or the edge of the RBW filter.

The offset channel definitions for single carrier operation and for the individual band classes are listed in the following tables.

Multicarrier Offsets

Multicarrier EV-DO ACP measurements perform offset power measurements of 30 kHz integration bandwidth at specific, partially band class-dependent offset frequencies. Offset frequency refers to the difference between the middle frequency of the multi carrier signal and the closer measurement edge frequency, or the edge of the RBW filter.
