Abstract :
The special testing signal generators were designed for a series of frequencies in the frequency band 0.5 to 20 MHz. The generator is very simple. It is composed of only one stable crystal oscillator and one high power amplifier. The frequency stability of the generators is in the order of 10-6/day, the output power is 1 W, the value of SINAD is under -130 dB and the total harmonic distortion is under -170 dB by using a linear narrowband filter.
