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(P_Tx + 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
