•
Eb/N0
– Received signal Eb/N0 measurement
•
Link Margin
– Estimated C/N of the received signal relative to the C/N in
EN 300-421 for a given Viterbi rate
•
Iturbi BER
– Error bits that the Viterbi error correction did not correct. BER
is measured over 10
7
symbols.
•
Frequency Tune
– The value is dependent on the mode selected in

Freq Drift Compensation
(see Section
4.2.2
and 7)
•
When Frequency Drift Compensation is set to
On
, the value of the frequency
tune displays the frequency of the incoming signal after frequency offset is
set to off.
•
When Frequency Drift Compensation is set to
Off
, the value of the frequency
tune displays the actual frequency.
N
OTE
Displayed frequencies are L-Band frequencies.
•
Frequency Offset
- Displays the offset from the frequency as was set in

Æ
Receiver
Æ
Frequency
(see Section
4.2.2
).
•
When Frequency Drift Compensation is set to On, the frequency offset
displays the value 0.
•
When Frequency Drift Compensation is set to Off, frequency offset displays
the value of the offset from the tuned frequency in KHz.
•
Viterbi Rate
– When Viterbi rate mode is set to automatic (see FEC Rate
parameter in section
4.2.2
), the value displayed is selected by the PVR 6000.
The Viterbi rate can also be configured manually to a specific rate by the
operator.
•
Spectral Inversion
– When the Spectral Inversion mode is set to automatic
(see Section
4.2.2
), the value displayed is PVR 6000 selected.
When you set the Spectral Inversion manually, the user selects the value.
