Research of Test and Sort System for Crystal Resonator

Yu Zhenhuan,Li Dong,Wang Yanlin(College of Optoelectronic Information & Telecommunication Engineering,Beijing Information Science & Technology University,Beijing 100192,China)  
This paper develops research of test and sort system for crystal resonator and makes a solution.The test and sort system is consisted of electronic parameters test system and sort system.The test system based on zero phase technique in a π-network which is recommended by IEC,can measure different electronic parameters of crystal resonator.By detecting the status of sensors,the sort system could accomplish feeding crystals,holding crystals in different areas of feed track,controlling the measurement contacts and sorting crystals.According to experiments,this system runs stably and accurately,the measuring accuracy of series resonant frequency is ±2ppm ranging from 1MH to 200MHz.This research is practical and worthy of using abroad.
