Abstract

A tuning fork crystal stability analyzer is characterized by comprising a to-be-tested tuning fork, a control chip, a keyboard circuit and a display, wherein the keyboard circuit is connected with aninput port of the control chip, the display is connected with an output port of the control chip, a control port of the control chip is connected with a relay, the control chip is also connected witha leakage current detection circuit and a frequency stability analysis circuit, and the to-be-tested tuning fork is selectively connected with the leakage current detection circuit and the frequency stability analysis circuit respectively through the relay. According to the scheme of the invention, the leakage current and the oscillation frequency of a tuning fork crystal are tested through the leakage current detection circuit and the frequency stability analysis circuit, test data and set data are compared and analyzed through the 51 single-chip microcomputer, and then an analysis result isdisplayed on a display screen, so that the whole testing process is very simple, the testing accuracy is high, and the result is absolutely clear.

Description

technical field [0001] The invention relates to a tuning fork testing device, in particular to a tuning fork crystal stability analyzer. Background technique [0002] In the field of quartz crystal production, it is necessary to analyze the stability of the quartz tuning fork crystal to avoid adverse reactions such as product failure and frequency jitter during use on the machine. In order to improve the stability of the quartz tuning fork crystal, in addition to its high-temperature aging treatment, it must be judged through electrical performance tests to eliminate unstable products so that the crystal can be used normally in different electromagnetic environments. At present, there is no special test and analysis tool in the field of tuning fork crystal production, and the test procedures are cumbersome and the accuracy is not high. Contents of the invention [0003] The purpose of the present invention is to overcome the defects and deficiencies of the prior art, and ...
