range (default is 1.23 MHz)
Absolute power accuracy for in-band signal
(excluding mismatch error), 18 °C to 30 °C
RF input
+30 to –28 dBm ±0.6 dB (±0.4 dB, typical)
–28 to –50 dBm ±0.8 dB (±0.7 dB, typical)
–50 to –80 dBm ±1.0 dB (±0.9 dB, typical)

power, input attenuator fixed) input level change
0 to –76 dB ±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.
