Abstract

The invention discloses a device for debugging reflection point resistance of a high stability oven controlled crystal oscillator. The device comprises a computer, a frequency meter, a rubidium atom frequency source and at least one layer of debugging frames. Each layer of debugging frames is provided with a crystal oscillator debugging panel and a radio frequency control panel. The crystal oscillator debugging panel and the radio frequency control panel respectively has a unique address code. The crystal oscillator debugging panel comprises a first encoder, a plurality of crystal oscillator seats and a digital potentiometer. The radio frequency control panel comprises a second encoder and a plurality of gating switches. Debugging software is installed on the computer, and the computer is used for recoding multiple resistance values of the digital potentiometer and multiple frequency values fed back by the frequency meter, determining an inflection point with the minimum frequency change according to the multiple frequency values, and obtaining a frequency of the inflection point and corresponding resistance of the frequency. Automatic debugging is achieved, accurate data can be obtained, and high production efficiency is achieved.

Description

technical field [0001] The invention relates to the technical field of crystal oscillator debugging equipment, in particular to an inflection point resistance debugging device and debugging method for a high-stability constant temperature crystal oscillator. Background technique [0002] The high-stability constant temperature crystal oscillator is an energy conversion element that converts a DC signal into a periodic oscillating signal. It uses the unique temperature smooth inflection point characteristics of crystal devices, and sets the inflection point temperature to keep the temperature constant, so as to achieve the resonance frequency. stability. In the production process of this kind of crystal oscillator, since the temperature inflection point of each crystal oscillator is inconsistent, it is necessary to adjust the temperature control point with a resistor matching it, and it takes a lot of time to debug the temperature inflection point of the crystal oscillator, s...
