Features: 1. Uses high-quality electronic components and precision manufacturing for enhanced durability and long service life. 2. 10 MHz constant-temperature output with ultra-low phase noise, low noise, portability, and reliability. 3. Features a 10 MHz frequency standard generated by an OCXO (oven-controlled crystal oscillator). 4. The OCXO maintains a stable internal temperature to minimize frequency drift caused by ambient temperature changes, enabling high-accuracy frequency reference performance. 5. Equipped with SMA female connector interface. Suitable for use with audio systems, decoders, shortwave radios, frequency counters, signal sources, and other test and measurement instruments.
