Downlink amplitude
Output port control: Control of RF source routing to either the RF IN/OUT port or the
RF OUT ONLY port
Composite signal level: The sum of the user-set values of the cell power and the AWGN
source measured in a root-raised cosine filter response with a roll off a = 0.22 and a
3.84 MHz BW; if the cell power is ON, the AWGN level must be set to within –20 dB to
+10 dB of the cell power. Note: The composite signal level is not settable, however it is
reported by the test set
RF IN/OUT cell power output range: –115 to –13 dBm/3.84 MHz
RF IN/OUT AWGN signal output level range: –115 to –20 dBm/3.84 MHz
RF IN/OUT VSWR:
–– < 1.14:1, 400 to 500, 700 to 1000 MHz
–– < 1.2:1, 1700 to 2000 MHz
–– < 1.4:1, 2000 to 2700 MHz
RF IN/OUT reverse power: +37 dBm peak (5 W peak)
RF OUT ONLY cell power output range: –115 to –5 dBm/3.84 MHz
RF OUT ONLY reverse power: +24 dBm peak (250 mW peak)
Measurement calibrate function: Calibrates the channel power, ACLR, SEM, waveform
quality, OBW, and code domain measurements over the specified frequency range of
the test set against the thermal power measurement, no external cabling is required to
perform this function
Measurement calibration time: < 180 seconds
Measurement calibration temperature range: Valid ±10 °C from previously
calibrated temperature
AWGN channel relative level range: Settable to –20 dB to +10 dB relative to the
user-set CDMA cell power with 0.01 dB resolution
