Description
ID
ID (1..63) of this bandwidth segment
Uplink and Downlink Beam
Beam ID of the beam containing this segments uplink frequency and
beam containing this segments downlink. Beams selected from the
Beams list. These must be defined on the Beams list.
Uplink and Downlink Center
Frequency
Center frequency of the uplink and downlink. These must fall within the
frequency ranges defined by the beams they are assigned.
Bandwidth
Bandwidth of this bandwidth segment.
EIRP
EIRP of this segment.
TFO
TFO for this segment
– read only.

Gain of this Bandwidth Segment
Transfer Gain
Total transfer gain for this bandwidth segment.
Saturated Flux Density
This field is measured in dBW/m
2
.
Input/Output Backoff
This field is measured in dB.
Total Transponder EIRP
This field is measured in dBW.
If using Saturated Flux Density the following calculation is performed to obtain Satellite
Transfer Gain in dB.
Transfer Gain: Gs(dB) = EIRP(dBW) + Gr(dB) + IOBO(dB) - SFD(dBW/m
2
)
where:
EIRP = saturated EIRP of the transponder
Gr = gain of a 1 square meter antenna at the uplink frequency
= (4 * Pi * A) / (lambda
2
)
where: A = 1 square meter
lambda = speed of light / satellite up center frequency
IOBO = I/O backoff in dB
SFD = Saturated Flux Density in dBw/m

.
