Additional Details:

The OCXO 143-146 typically operates at a specific frequency, such as 10 MHz or 100 MHz. It requires a stable DC power supply to operate the oven and oscillator circuits. The oven temperature is typically set to a value slightly above the maximum operating temperature to ensure stable operation. The device is typically housed in a hermetically sealed package to protect the crystal from environmental factors. The output signal is typically a sine wave or a square wave, with a specified amplitude and impedance. The OCXO's performance is characterized by its Allan variance, which measures the frequency stability over different time intervals. Detailed specifications, including frequency stability, phase noise, and aging rate, are available from Taitien's datasheet. Proper grounding and shielding are essential for minimizing noise interference. Regular calibration is recommended to maintain optimal performance.
