Constant rate sweep frequency generator |
摘要 |
A variable frequency oscillator including a nonlinear element for varying the frequency has alternately attached thereto a phase lock loop for maintaining the base or starting frequency of the oscillator substantially constant, and a sweep generator with a rate error loop for sensing the frequency linearity of the output sweep and altering the input signal to maintain the output linear.
