C5/K1/K3 Integrated Satellite Terminal System Specifications
Rev. 0 2–21
2.2.4.5 Transmit IF Power
1. The transmit power is operator-selectable from +17 to +30 dBm or +22 to +35
dBm, in 0.1 dB steps.
2. The maximum drift due to temperature change is
%
0.75 dB. (The ALC feature of
the ODU is used.)
3. The transmit power accuracy is
% 2.0 dB at minimum power and % 1.5 dB at
maximum power.
4. The transmit output is flat within 0.2 dB over any 1 MHz segment.
2.2.4.6 Modulated Output Shape
The terminal meets the following transmit output spectral mask specifications, subject to
the limitations of a 50 dB S/N ratio. The desired mask is selectable from the front panel or
remotely.
( Closed Network (EFData/Comstream)
( Closed Network (Fairchild compatible)
2.2.4.7 Spurious Emissions
Spurious emissions are measured at the Ku-Band ODU output Type N female connector.
The measurement is done with the carrier ON, in continuous mode, and modulated by the
correct data/clock signal.
1. Spurious emissions measured in a 3 kHz bandwidth at the transmit output are
" -13 dBm from 10.7 to 15 GHz., excluding a band % 1 MHz from the carrier.
2. Spurious emissions measured in a 3 kHz bandwidth from 10.95 to 12.75 GHz are
" -126 dBm.
3. The carrier is suppressed to
" -35 dBc in normal operating mode.
4. The undesired sidebands of the modulated signal is suppressed to
" -30 dBc.
5. The harmonics of the modulated signal is
' -20 dBc.
