This system is based on FPGA ( EP2C8Q240C8 ) as the control core, by a voltage controlled oscillator, PLL multiplier, high frequency power amplifier, remote control and LCD display module comprising a voltage-controlled LC oscillator. Can realize the output sine wave frequency in the step 15MHZ~35MHZ is adjustable, the smallest Bu Jin 5002HZ, frequency stability 10-5. When the frequency of the output signal is 30MHZ, peak stable at about 1V, in+12V single supply situation, the power amplifier can be realized in 50 Ωto 50 Ω+20pf pure resistive and capacitive load on the output power is greater than 20mw. LCD display module can display the output signal and the peak frequency, precision due to 10 .
