Power |
P |
Scalar or Distribution |
dBm |
This is the transmitter power supplied to the antenna of the generic system, including feeder loss. |
|
Interfere is CR: |
|
Boolean |
|
When the CR button is checked then it allows to set the emission characteristics of the VLT and ILT (used for the sRSS calculation only. See Section 6) |
|
Emission mask:
|
emission_rel(f) |
Function (X,Y) (kHz)
|
dBc/ reference bandw. (kHz) |
Define the mask of the transmitter, in the emission bandwidth and out of the emission bandwidth. It is the unwanted signal level from the ILT. (See ANNEX 7:) |
|
Unwanted emissions floor: Noise floor signal level |
emission_floor(f) |
Function (X,Y) (kHz) |
dBm/ reference bandw. (kHz) |
Define the minimum strength of the unwanted emissions. So the unwanted emissions equal to Max(PTx + Unwanted emission, Unwanted emissions floor) (see Annex A7.4) |
|
Power control |
|
|
|
If Power control is checked, the 3 following parameters have to be defined. This Power control is used to limit the output power of the transmitter (see ANNEX 14:) |
|
Power control step size |
PC step |
Scalar |
dB |
|
|
Min threshold |
PC threshold |
Scalar |
dBm/ emission bandw |
If the received power is lower than this threshold, then no power control takes place |
|
Dynamic range |
PC dyn |
Scalar |
dB |
If the received power is higher than Pc treshold + Pc dyn then the full power control takes place, i.e. the power is decreased by Pc dyn |
