Channel frequency generator for use with a multi-frequency output generator |
摘要 |
An apparatus and method is disclosed which phase locks a frequency-agile modulated output signal to any selected channel of a comb generated output. The phase error of an input signal is tracked, the input signal is modulated up to a carrier output frequency, and the modulated output frequency is locked to the comb generator output by subtracting the input signal and negating the phase error.
