A real-time on-line automatic debugging and measuring system for microcomputer compensa-ted crystal oscillator (MCXO)was designed.The system integrates the S&A4220 temperature test cham-ber,a high precision frequency counter,a personal computer,and a special microcontroller based on C8051F061 with 8 measuring channels.The control program on PC was designed by means of Labview. All main technical parameters of MCXO can be measured automatically with this system.Within the tem-perature range (-40 ℃ to +85 ℃),the frequency-temperature stability of developed MCXO is ≤±7× 10-8 .
