14.6.13 Monitoring Parameters
The monitoring parameters provide a global overview of the incoming signal.
Parameter Description
Carrier Input
Level
This indicates the power level measured of the carrier. When the carrier uses
a part of the transponder, the measured level is smaller than the value
measured for the full input range.
EsN0 Signal to noise ratio of the satellite link.
L-Band Input
Level
This indicates the power level measured over the total input range in dBm.
Phase Noise
Indication
Phase noise indication (expressed in degrees).
Phase noise indicates fluctuations phase of the carrier.
Offset to
reference
Mask
The following is formula is applied:
Integrated Phase Noise (degr) / Reference Mask Phase Noise (degr).
This monitoring parameter compares the 'Integrated Phase Noise' estimator
with a reference phase noise mask.
The mask is considered as what is worst case reference for a professional
grade system. The target value is shown in the table next to it.
The following table displays the difference between the worst case reference
and the target value per measured frequency.
Frequency
Phase Noise level [dBc/Hz]
Worst Case Reference Target Value
10 Hz -27 -32.9
100 Hz -45 -61.9
1 kHz -65 -78.7
10 kHz -75 -88.7
