Adopts premium electronic parts, with accuracy process, which ensures fine durability and long service time. Constant temperature 10MHz, ultra-low phase noise, low noise, portable and . This product adopts 10MHz frequency standard, and which is provided by OCXO controlled crystal oscillator. Constant temperature crystal oscillator means this product uses a constant temperature bath to keep the temperature of a crystal oscillator or a quartz crystal oscillator constant, so the change in the output frequency of the oscillator caused by changes in the surrounding temperature is reduced to a minimum, which makes it has higher accuracy, 0.01Hz. Equipped with SMA outer screw inner hole interface. Wide applications, which can be used for instrument benchmarks such as audio , decoders, shortwave radios, frequency , signal sources, etc. Name: Frequency Reference Source Current consumption: preheating stage Less than 750mA, working stage Less than 300mA Warm-up time: 5 minutes Calibration accuracy: 0.01Hz Frequency stability: 5e-12 Output level: dBm: 10dBm2dBm@50 VRMS: 0.7071V@50 VPeak: 1.0V@50 -P: 2.0V@50 Output impedance: 50 Interface type: SMA outer screw inner hole Item size: 67 x 58 x 14mm / 2.64 x 2.28 x 0.55inch Item weight: 40g / 1.41ounce 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 are not included.
