A real-time on-line automatic debugging and measuring system for microcomputer compensated crystal oscillator(MCXO)was designed.The system integrates the SA4220temperature test chamber,a high precision frequency counter,apersonal computer,and a special microcontroller based on C8051F061with 8measuring 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 temperature range(-40 ℃to +85 ℃),the frequency-temperature stability of developed MCXO is≤±7× 10-8.
