| titleOfInvention | Test circuit and test device for quartz resonator |
| abstract | The invention discloses a test circuit and a test device for a quartz resonator, wherein the circuit comprises: the quartz resonator to be tested is connected between the frequency adjusting module and the frequency broadening network module. The invention achieves the purpose of truly simulating the load condition of the quartz resonator by connecting the actual element in the oscillation loop of the crystal oscillator in series in the branch of the quartz resonator, expands the load types in the commercial quartz resonator testing device, and can improve the accuracy of judging whether the quartz resonator is suitable, moreover, the circuit of the invention can make partial elements fail by means of short connection and the like, thereby simulating different real environments, and further having wider applicability. |
