Abstract
Methods and systems for frequency generation may comprise receiving a satellite signal the satellite signal having a center frequency; determining an amplitude response profile of the satellite signal; and computing the center frequency of the satellite signal based on the amplitude response profile of the received signal; and generating a reference signal at the computed center frequency. A center frequency of each of a plurality of satellite signals may be computed based on the computed center frequency. The determining the amplitude response profile may include: sweeping a tuner above and below a given reference frequency; measuring the received signal strength during the sweeping operation; and determining upper and lower rolloff points of the signal based on the measured signal strength.
