Conclusions:
Based on measurements obtained lower loop capture range - 35 kHz. The upper range could not be determined. Loop bandwidth can be increased capture of expanding bandwidth loop filter. However, this leads to a reduction of resistance to interference. Once submitted, the characteristics were obtained keeping the scope of the loop. It ranged from 5 kHz to 150 kHz. The slope characteristics kVCO = 0022 V / kHz - is the voltage conversion ratio - the frequency generator. The test loop was not possible to verify the ability to synchronize the harmonic frequencies. Free vibration frequency VCO was about 36 kHz.
