Parameter
Description
For the comparison the reference phase noise is integrated within the correct
bandwidth (the bandwidth used by the phase noise estimator). The phase
noise estimator is compared to the reference and the difference is expressed
in dB.
Non linearity
This value provides an indication of the non-linearity of the carrier in %.
Indication
Symbol Rate
Displays the symbol rate measured on the input interface.
Carrier Offset
Displays the frequency offset between the actual (tracked) frequency and the
set frequency.
Frame Counter
Displays the amount of incoming frames.
Dummy Frame
Displays the amount of dummy frames that are transmitted over the satellite
Counter
link.
Errored Frame
Displays the amount of error frames.
Counter
Cycle Slip
A cycle slip occurs when the symbol phase tracking loop fails.
Frame Counter
Cycles slips indicate that system phase noise affect performance.
Phase discontinuities due to a local oscillator stability issues will also be
reflected in cycle slips.
Also check if the LNB is still working as expected.

In practice the target value is about -4 to -14 dB better than the
worst case reference.
