A CHANNEL FREQUENCY GENERATOR FOR USE WITH A MULTI-FREQUENCY OUTPUT GENERATOR

摘要

The invention relates to a method and apparatus which carry out the phase locking of a modulated output signal frequency agile on any selected output channel (25) of a generator of the comb type. The phase error of an input signal (14) is continued, the input signal is modulated onto a carrier frequency and output the modulated output frequency is locked to the output of the comb-type generator by subtracting the input signal and performing a logical inversion of the phase error.
