Hi,


I am testing new card TBS 6528. It is multistandar with support for DVB-C annex B. I setup the card with the following command


sudo dvb-fe-tool -a 2 -f 0 -d DVBC/ANNEX_B



I am simulating the signal with a Dektec DTA-2111. DtPlay command is


DtPlay file.ts -l 0 -r 15000000 -t 2111 -m 188 -mt QAM64 -mf 482 -ml -35.0dBm -ma B -snr 26.0



I think there is support for DVB-C annex B in source code:

but when executing "dvblast --help" I only see the following delivery systems:
DVBS|DVBS2|DVBC_ANNEX_A|DVBT|DVBT2|ATSC


I execute dvblast with the following options

dvblast -f 482000000 -s 6900000 -a 2 -5 DVBC_ANNEX_B


but I am not able to tune.


Any idea?


Best regards.

Gonzalo.
