ZXSDR BS8802 C100 User Guide
Table 3-3 illustrates the 1.9 GHz transmitter indices.
Table 3-3 1.9 GHz Transmitter Indices
Name Index
Operating band 1.9 GHz (Band Class 1)
Transmitter output frequency tolerance ± 0.01 ppm
Occupied channel bandwidth 1.25 MHz
Output power at the Top of Cabinet
(TOC)
600 mW
Total transmit power
The total transmit power is 2 dB and -2 dB of the
manufacturer’s rated power.
Modulation mode Quadrature amplitude modulation
Conducted spurious emission and
radiated spurious emission suppression
< -45dBc @±885 kHz offset Center Freq (RBW 30kHz)
< -55 dBc @±1.98 MHz offset Center Freq (RBW 30kHz)
> 4 MHz OFFSET:
< -36 dBm (RBW 1kHz) @ 9KHz < f < 150 kHz
< -36 dBm (RBW 10kHz) @ 150 kHz < f < 30 MHz
< -36 dBm (RBW 100kHz) @ 30 MHz < f < 1 GHz
4-16 MHz OFFSET:
< -30 dBm (RBW 30kHz) @ 1 GHz < f < 12.5 GHz
16M-19.2M OFFSET:
<-30dBm(RBW 300kHz) @ 1GHz < f < 12.5GHz
>19.2MHz OFFSET:
<-30dBm(RBW 1MHz) @ 1GHz < f < 12.5GHz
Transmitter intermodulation
performance
If one BTS transmits at the rated power but another BTS’
output power is 30 dB less than the former’s rated power.
When the powers of two BTSs are combined on the antenna
port, the generated intermodulation spurious emission
meets the conducted spurious emission requirement. The
IF difference of the transmit signals of two BTSs is 1.25 M.
Pilot time tolerance
The PN time tolerance falls within 3 us and the inter-carrier
tolerance falls within 1 us.
Time difference: < ±50 ns
Time Tolerance/phase tolerance of pilot
channel to other channels
Phase difference: < 0.05 rad
Waveform quality
Rho is greater than 0.990 dBm under the configuration of
a single pilot.
Pilot code domain power
With the standard 9CH configuration, the pilot code domain
power is in the range of -7.0±0.5 dB.
