RF IN/OUT composite signal absolute output level accuracy
AWGN on:
–– < ±1.2 dB, at –80 to –20 dBm/3.84 MHz and < 2300 MHz,
typically < ±0.75 dB, over –109 to –20 dBm/3.84 MHz and < 2300 MHz
–– < ±1.6 dB, at –80 to –20 dBm/3.84 MHz and ≥ 2300 MHz
typically < ±1.1 dB, at –109 to –20 dBm/3.84 MHz and ≥ 2300 MHz
RF OUT ONLY cell power absolute output level accuracy
AWGN off:
–– < ±1.1 dB, at –109 to –7 dBm/3.84 MHz and < 2300 MHz
typically < ±0.65 dB, –109 to –15 dBm/3.84 MHz
–– < ±1.5 dB, typically < ±1.0 dB, at –109 to –15 dBm/3.84 MHz and ≥ 2300 MHz
RF OUT ONLY composite signal absolute output level accuracy
AWGN on:
–– < ±1.2 dB, at –80 to –12 dBm/3.84 MHz and < 2300 MHz
typically < ±0.75 dB, at –109 to –20 dBm/3.84 MHz and < 2300 MHz
–– < ±1.6 dB, at –80 to –20 dBm/3.84 MHz and ≥ 2300 MHz
typically < ±1.1 dB, at –109 to –20 dBm/3.84 MHz and ≥ 2300 MHz
Common pilot channel relative level: –20 to 0 dB
Primary sync channel relative level: Always the same as P-CCPCH
Secondary sync channel relative level: Always the same as P-CCPCH
Primary CCPCH relative level: –20 to 0 dB
DPCH relative level: Settable from –30 to 0 dB with 0.01 dB resolution
PICH relative level: –20 to 0 dB
Downlink CDMA modulation
Modulation type: QPSK per 3GPP standard
Residual EVM: < 10%, typically < 3%
Carrier feed through: < –25 dBc, typically < –35 dBc, nominal ambient performance: < –45 dBc
OCNS – orthogonal channel noise source
Composed of 16 channels per Table E.3.6 in Annex E of 3GPP 34.121
OCNS channel relative level range: Automatically calculated from other
code channel relative levels to provide the set CDMA cell power
Relative CDMA channel level accuracy: < ±0.2 dB
