Abstract :
An automatic temperature compensated crystal oscillator (TCXO) frequency-temperature test apparatus was developed using a thermoelectric device array. The developed system swings stably the test temperature range from -40°C to 80°C for about 1 hour. The rising temperature ratio was fairly linear with time in this test temperature range. The temperature could be controlled in an error range of ±0.05°C in this system. The developed system could be used for measuring the accuracy of frequency-temperature properties of TCXO or the thermoelectric properties of other electronic devices
