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 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 :ELECTRICAL Model Number:OCXO-10MHz DSD Sampling Frequencies: 2.8224 MHz (DSD64) PCM Word Length: 16-bit PCM Sampling Frequencies: 44.1 kHz Outputs: RCA Inputs: USB Type-A Type: Desktop color:Black Material:ABS Package Contents: 1 x Frequency Reference Source Only the above package content, other products are not included.
