The details of the design and construction of an injection and frequency locked super-regenerative oscillator ( SRO ) type NQR spectrometer working in the frequency range of 13MHz-40MHz are presented. The spectrometer is composed of external quench super-regenerative-oscillator, a continuous wave oscillator with stability of about 10(-5) and a frequency locked unit. The quench frequency can be continuously adjusted from 15KHz to 150KHz. The advantages of the spectrometer are as follows. ( I) the pure absorption or pure dispersion line-shapes can be obtained separately ( ii ) its frequency stability is determined only by that of an independent oscillator which provides a frequency locking signal ( iii ) the resonant frequency can be measured directly by a frequency counter.
