DVB-S MER, BER and Offset Measurement

The modulation error rate (MER), the bit error rate (BER) and the carrier offset can be measured to rate the digital reception quality. Chapter ‚standard change-over‘ describes how to select between SAT/analogue and DVB-S.

Calling up DVB-S measurement:

Press [2ndF] [DVB] in SAT reception mode

LC display:


MER:12.6dB	MHz
BER:1.7e-7	+ 0.72

•(MER) modulation error rate: 12.6 dB

•(BER) bit error rate: 1.7e-7

•Carrier offset +0.72 MHz

In case there are no bit errors identified due to a strong DVB signal,

BER=0.0e+0 is indicated on the display.

MPEG Picture Representation (option) in DVB-S

After selecting DVB measurement by pressing [2ndF] [DVB], the list of programmes received via digital transport data stream is displayed on the TFT screen.

Press [+] or [-]to select the desired programme and confirm your entry by pressing [Enter].

In case of an FTA programme, picture and sound of the desired programme are decoded and represented or reproduced respectively via the loudspeaker which is built in.

Select another programme on the list by pressing [Enter] once more.

Press [2ndF] to exit digital reception.

Note

For measuremts exceeding 100 dBµV please use the enclosed ☞ attenuation plug, as otherwise no video representation and no MER and

BER measurements are possible.

(Find indications on the frequency response of the enclosed attenuation plug on the last page)
