Monitoring the DVB
-S/S2 Input Port Properties
To monitor the ProView 7000™ reception parameters:
1. Navigate
Root > Reception
.
2. If your device has more than one demodulator, select a satellite input menu, SAT 1–4.
3. Select
Status
.
The reception status displays whether the physical port is connected or not to the DVB
Multiplex In.
NOTE:
Some of the parameters apply to DVB-S or DVB-S2 modes only. They are displayed according to the
mode used.
The Status menu comprises the following:
■
C/N
– displays the measured carrier to noise ratio [dBc]
■
Eb/N0
– displays the measured energy per bit to noise power spectral density ratio [dB]
■
Link Margin
– displays the measured link margin level [dB]
■
BER
– DVB-S only. Display the bit error rate detected.
■
PER Value
– DVB-S2 only. Display the packet error rate detected. The BER/PER error rate is
a decimal number x 10-X (therefore, a.b E-X).
■
Carrier Locked
– displays the carrier locking status: Locked (Yes) / Unlocked (No)
■
Demodulator Locked
– displays the demodulator locking status: Locked (Yes) / Unlocked
(No)
■
Tuned Frequency
– displays the reception tuned frequency [MHz]
■
Frequency Offset
– displays the reception frequency offset from configured frequency
[MHz]
■
Spectral Inversion
– displays the spectral inversion function operational status. Options:
Normal or Inverted
■
Modulation
– Displays the reception modulation type
■
FEC Rate
– displays the coding rate of the input modulation
■
Pilot
– DVB-S2 only. Displays the pilot signals injection status (On/Off)
■
Frame Size
– DVB-S2 only. Displays the size of the received frame.
Options: Normal (64,800 bits frame) or Short (16,200 bits frame)
