Adopts high-quality electronic components with precise processing, ensuring durability and extended service life. Constant temperature 10MHz, ultra-low phase noise, low noise, portable, and reliable. This product features a 10MHz frequency standard, provided by an oven-controlled crystal oscillator. The constant temperature crystal oscillator utilizes a temperature-controlled bath to maintain the temperature of the crystal oscillator or quartz crystal, minimizing output frequency variations due to surrounding temperature fluctuations, resulting in higher accuracy of 0.01Hz. Equipped with an SMA outer screw inner hole interface. Versatile applications, suitable for instrument benchmarks such as audio systems, decoders, shortwave radios, frequency meters, signal sources, etc. Name: Frequency Reference Source Current consumption: preheating stage less than 750mA, operating stage less than 300mA Warm-up time: 5 minutes Calibration accuracy: 0.01Hz Frequency stability: 5e-12 Output level: dBm: 10dBm, 2dBm @ 50V RMS: 0.7071V @ 50V, Peak: 10V @ 50-P: 20V @ 50 Output impedance: 50 Interface type: SMA outer screw inner hole Item size: 67 x 58 x 14mm / 2.64 x 2.28 x 0.55 inch Item weight: 40g / 1.41 ounce DIY Supplies: ELECTRICAL Model Number: OCXO-10MHz Color: Black Material: Plastic Package Contents: 1 x Frequency Reference Source 1 x Cable Only the above package content, other products are not included.
