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.
