ABSTRACT:
A frequency source for sequentially generating several output signals of different frequencies, which includes a permanent frequency table, a digitally stored frequency table and a single stabilization circuit for updating the digitally stored frequency table using the permanent frequency table and the output frequency. The source further includes the ability to convert the digitally stored frequency to the generated output frequency; and a clock for synchronizing the updating of the digitally stored frequency table. In certain embodiments the source further includes a sampler for sampling the output signal and a feedback mechanism for feeding back the output signal to the stabilization circuit.
