SAT
DVB-S(2) MER, 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 button to select between SAT analogue and SAT
digital.
Calling up DVB-S(2) measurement:
In SAT digital reception mode press the 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 = DVBS2
• 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.
