SAT
DVB-S(2) MER-(=SNR), BER AND OFFSET MEASUREMENT
The modulation error rate (MER), the bit error rate (BER) and the
carrier frequency offset (LNB offset) can be measured to rate the
digital reception quality.
Note:
In this case MER shown on the display has the same
meaning as SNR (signal radio ratio).
Use the
[SAT A/D]
button to select between SAT analogue and
SAT digital.
Calling up DVB-S(2) measurement:
In SAT digital reception mode press the
[DVB]
button.
LC display:
• MER modulation error rate:
12.6 dB
• Modulation type
8PSK
• Code rate
9/10
• BER bit error rate: 1.7e-7
• Standard = DVB
S2
• Carrier frequency offset (LNB offset):
+0.72 MHz
If the quality of the DVB signal is so good that no bit error can be
detected,
BER=0.0e+0
is displayed.
MPEG IMAGE REPRESENTATION IN DVB-S(2)
If you select DVB measurement by pressing
[DVB]
the TFT screen
displays the list of programmes that can be received on the digital
transport stream.
Use the
[<]
or
[>]
key to select the desired programme and confi rm
your selection by pressing
[OK]
.
To select the programme, you can also enter the displayed
programme number directly:
[0]
[1]
...
[OK]
.
If the programme can be received free of charge, the picture and
sound of the desired programme are decoded and displayed or
played back via the integrated speaker.
By pressing
[OK]
again you can select another programme from the
programme list.
Press [DVB] to exit digital reception.
LNB VOLTAGE AND 22 KHZ/60 HZ CHANGE-OVER
The LNB supply voltage is available at the RF socket. To turn on or
change the LNB voltage, press the
[LNB CNTRL]
button.
The LNB voltage
• can be switched off = 0V
• can be adjusted from 5 V to 20 V in 0.1 V intervals
• is short-circuit proof (max. amperage 600 mA from 5 to 20 V)
