In a method of tuning a receiver for a digital signal (MPEG2-TS), an input signal (RF-in) is filtered (In-filt, Band-filt) to obtain a processed signal, a digital figure of merit (BER) is determined (Mix/Osc/IF amp IF-downconv-2, C) from the processed signal, and the filtering step (In-filt, Band-filt) is fine-adjusted (muP, PLL, DAC1-DAC3) in dependence on the digital figure of merit (BER).
