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 oven controlled crystal oscillator.Constant temperature crystal oscillator means that this product uses a constant temperature bath to keep the temperature of a crystal oscillator or a quartz crystal oscillator constant, so that 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 SourceCurrent consumption: preheating stage Less than 750mA, working stage Less than 300mAWarm-up time: 5 minutesCalibration accuracy: 0.01HzFrequency stability: 5e-12Output level: dBm: 10dBm2dBm@50VRMS: 0.7071V@50VPeak: 1.0V@50-P: 2.0V@50Output impedance: 50Interface type: SMA outer screw inner holeItem size: 67 x 58 x 14mm / 2.64 x 2.28 x 0.55inchItem weight: 40g / 1.41ounce:ELECTRICALModel Number:OCXO-10MHzcolor:BlackMaterial:plasticPackage Contents:1 x Frequency Reference Source1 x CableOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the a little different from the real thing.
