5.3.5 Emission characteristics

This panel consists in setting of the emission characteristics of your generic system.

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
