TD-SCDMA RF generator
Frequency ranges (MHz):
Band 34: 2010 to 2025
Band 39: 1880 to 1920
Band 40: 2300 to 2400
Band 41: 2496 to 2690
Frequency/Channel setting: By channel number or MHz (test mode only)
Frequency accuracy: Same as timebase reference
Frequency setting resolution: Typically 1 Hz
Output port control: Control of RF source routing to either the RF IN/OUT port or the
RF OUT ONLY port
RF IN/OUT cell power output range: –115 to –13 dBm/1.28 MHz
This range is the hardware range with amplitude offset = 0. The actual power range is
defined by adding the value of associated amplitude offset to the range in the table
RF IN/OUT AWGN signal output level range: –115 to –15 dBm/1.28 MHz
RF IN/OUT VSWR:
< 1.14:1, 400 to 500 MHz and 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/1.28 MHz
RF OUT ONLY reverse power: +24 dBm peak (250 mW peak)
Absolute output level accuracy: < ±1.2 dB
RF output EVM: < 10%, typically < 3%
Carrier feed through: < –25 dB, typically < –35 dB
Downlink channel power level: All downlink timeslot power levels are fixed to the
cell power. The physical channels in one timeslot have separate relative powers and
the relative power of the channels in one timeslot must sum to 100% of the timeslot
power. In test mode, power levels and states of all downlink channels are fixed except
DPCH and DPCHo
Downlink pilot on DwPTS relative level: 0 dB
AWGN channel relative level range: Settable to –25 to +10 dB relative to the user-set
CDMA cell power with 0.01 dB resolution
Primary CCPCH relative level: –3 dB
PICH relative level: –3.02 dB
DPCH relative level: Settable from –30 to 0 dB with 0.01 dB resolution
DPCHo channel relative level: Automatically calculated from the relative level of DPCH
to provide the set cell power
Downlink CDMA modulation type: QPSK per 3GPP standard
Modulation type: QPSK per 3GPP standard
QPSK residual EVM: < 10%, typically < 3%
QPSK carrier feed through: < –25 dBc, typically < –35 dBc
