Measurement of delays in quadripoles by means of the autogeneration method with a delayed feedback is attractive owing to the simplicity of its measurements and high sensitivity with respect to small phase increments. Oscillation-frequency variations are set precisely by adjusting the feedback circuit phase shifts δϕ=0.01−0.001‡ and thus ensuring an oscillator stability of the order of 10−6. The advantage of this method consists of measuring the GDT at the actual dispersion-standard tuned working frequency, i.e., without the signal-frequency conversion, which normally entails distortion of the information on the phase shift in the measured quadrupole. By taking advantage of the suggested technique for obtaining the oscillator PFC and using the known oscillator phase shift, it becomes possible to raise the precision in measuring quadrupole delays and measure delays of ∼10 nsec over a wider frequency range than that of [1]. Moreover, the evaluation of the oscillator PFC with a delayed feedback has a practical value in other measurements, for instance, in measuring permittivity by means of the autogeneration method.
