According to the datasheet, the carrier to noise ratio for the BSRU6 front end, (which contains an stv0299), can be calculated in dB using the following information: Register ADD 24 NIRH 8 bits (MSB of noise indicator) Register ADD 25 NIRL 8 bits (LSB of noise indicator) C/N (dB) = -0.0017 * NIR + 19.02 Regards, Richard _______________________________________________ linux-dvb mailing list linux-dvb@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
