±0.2 dB (±0.1 dB, typical)

Code domain measurement (base station)

Code domain measures the power, timing, and phase, of
each of the 64 Walsh channels in an cdmaOne base-station
transmitter. Code-domain power is measured for each Walsh
channel relative to the total power inside the 1.23 MHz
channel. Code-domain phase is the measured phase error
for each Walsh channel relative to the pilot channel. Code-
domain timing is the measured timing error for each Walsh
channel relative to the pilot channel. Time offset, frequency
error, and carrier feedthrough are also measured.
