Code Domain Power (Power)
Code domain power displays the power in each of the 64 Walsh
channels, relative to the total power inside 1.23 MHz bandwidth
centered at the tune frequency. The 64 Walsh codes (0 through 63) are
represented by a vertical bar on the analyzer’s display. Because this is a
relative measurement, the unit-of-measure is always dB. This allows a
comparison of signal levels between the pilot, sync, paging and traffic
channels. (Pilot is about two-thirds of the total energy.)
