Signal monitoring

Hello,

Do you guys have any experience in signal monitoring with the card in linux?

I am using dvbsnoop to measure the signal. The result is something like this:
cycle: 1045 d_time: 0.180 s Sig: 65500 SNR: 65500 BER: 0 UBLK: 0 Stat: 0x1f [SIG CARR VIT SYNC LOCK ]
cycle: 1046 d_time: 0.240 s Sig: 65500 SNR: 65500 BER: 0 UBLK: 0 Stat: 0x1f [SIG CARR VIT SYNC LOCK ]
cycle: 1047 d_time: 0.210 s Sig: 65500 SNR: 65500 BER: 0 UBLK: 0 Stat: 0x1f [SIG CARR VIT SYNC LOCK ]
cycle: 1048 d_time: 0.240 s Sig: 65500 SNR: 65500 BER: 0 UBLK: 0 Stat: 0x1f [SIG CARR VIT SYNC LOCK ]
cycle: 1049 d_time: 0.210 s Sig: 65500 SNR: 65500 BER: 0 UBLK: 0 Stat: 0x1f [SIG CARR VIT SYNC LOCK ]
cycle: 1050 d_time: 0.180 s Sig: 65500 SNR: 65500 BER: 0 UBLK: 0 Stat: 0x1f [SIG CARR VIT SYNC LOCK ]

I presume Sig is for signal and SNR is Signal to Noise Ratio. How should I understand those values? Is there a way to "convert" to dBm?

Thanks.
