1. Premium Electronic Components: This electronic components is constructed with high-quality electronic components, ensuring high precision, durability, and a long lifespan. 2. Stable 10MHz Output: The sound decoder frequency meter provides a constant temperature-controlled 10MHz output with ultra-low phase noise, delivering low noise performance that is reliable and portable. 3. Temperature Compensation for Precision: The temperature-controlled crystal oscillator (OCXO) in this ocxo 10mhz frequency standard reference module maintains a constant temperature using a temperature-controlled chamber. This reduces frequency fluctuation caused by temperature changes to a minimum, resulting in higher accuracy with a deviation as low as 0.01Hz. 4. Equipped with SMA Interface: The ocxo frequency reference board comes with an SMA external screw inner hole interface, allowing easy and secure connections. 5. Wide Range of Applications: This ocxo-10mhz frequency reference module is versatile and can be used as a benchmark test for audio systems, decoders, shortwave radios, frequency counters, signal sources, and other inst ents. Its precision and stability an ideal choice for various DIY projects.
