Abstract :
Oven controlled crystal oscillators (OCXO) have been widely used in global positioning systems, communications, metering, telemetry control, spectrum, network analyzers and other electronic equipments as a source of time-frequency signal with high precision. Two most important performance indexes of a crystal oscillator are frequency stability and start-up characteristics. In this paper the marriage of hardware and software, practice of dual thermostatic bath and application of optimization technology in temperature control in duel temperature control system enable quicker start and further improve temperature control accuracy and the frequency stability of OCXO. This clever design optimization achieves lower power consumption, higher stability, even more compact size and quicker start.
