Amplitude
Output port control: user control of RF source routing to either the
RF IN/OUT port or the RF OUT ONLY port

the CDMA cell power and the AWGN source power

performance to −15 dBm/1.23 MHz
RF IN/OUT CDMA cell absolute output level accuracy (AWGN
off): RF generator level accuracy is derived from 99^th percentile
observations with 95 percent confidence (corresponds to an
expanded uncertainty with a 95 percent confidence (k=2)) at
ambient conditions, then qualified to include the environmental
effects of temperature and humidity.
