W-CDMA Measurement Application
Amplitude
d. If 16 QAM and 64 QAM codes are included, it is not applicable.
e. This specifies a synchronization range with CPICH for CPICH only signal.
f. tfa = transmitter frequency × frequency reference accuracy
g. The accuracy specification applies when the measured signal is the combination of CPICH (antenna−1)
and CPICH (antenna−2), and where the power level of each CPICH is −3 dB relative to the total power
of the combined signal. Further, the range of the measurement for the accuracy specification to apply is
±0.1 chips.
