As shown in figure, the circuit uses the characteristic of zener breakdown of the VR-tube to get high frequency signals amounting to hundreds of megahertz. Single frequency signals from the output end V01 can be used to adjust the resonant frequency of the tuning circuits. High frequency signals of broad spectrum from output end V02 can track between the input resonant circuits and the local oscillator tuning circuit of uperheterodyne resonant receiver. The frequency range of the generator is 100kHz ~ 27 MHz, which is divided into five frequency range :100kHz～300kHz～1MHz～3MHz～9MHz～27MHz.
