AfterDark. Project ClayX GIESEMANN OCXO 10MHz Trifecta Ultra Edition  

產品特點         

  • 該產品採用的OCXO,並通過長期校準來選擇並安裝具有出色穩定性的設備。
  • OCXO單元增加了由Dynamat Extreme Corporation (Made in USA) 成Audio Grade的隔熱Anti-Shock Material,KEMET EMI Shielding + 外層添加由真皮製成的隔熱, 以保持OCXO的性能最大化。
  • 機箱的底部由3毫米厚的BLACK MATT鋁材料 +2mm碳纖維材料製成,具有堅固的振動控制結構。另外,使用厚度為3mm /6mm的碳纖維材材料在板周圍構造了堅固的磁屏蔽。
  • 使用高度校準的測量儀器旗艦Symmetricom 5125A嚴格測量特性。通過繪製每個單元輸出處的Phase Noise相位噪聲和Allan Deviation艾倫方差來保證時鐘質量。 
  • Hand Made in Hong Kong 
  • 兩年的免費維修保修。  

終極等級選擇值

  • 產品中安裝的OCXO可長時間校準工業設備中使用的產品,並使用特性良好的設備。為了最佳地選擇音頻時鐘, 高度校準的測量儀器旗艦Symmetricom 5125A嚴格測量特性。通過繪製每個單元輸出處的Phase Noise相位噪聲和Allan Deviation艾倫方差來保證OCXO時鐘質量。   

等級選擇值 

  • 本產品中安裝的OCXO使用已校準幾個月的穩定OCXO單元。為了進行音頻時鐘的最佳選擇,我們正在對相位噪聲特性和短期穩定性(艾倫色散)進行全面評估,以便進行更詳細的檢查。最終產品將參考Keysight 53220A原子鐘GPSDO進行最終測量和微調。

選擇基準值
Phase Noise 相位噪聲:偏移1 Hz時為-100至-121dBc / Hz或更低(Grade 區分)偏移10 Hz時為-145 dBc / Hz或更低

Features 
The product uses the selected audio grade OCXO, and through long-term calibration to select and install equipment with excellent stability.

  • OCXO that employs with quantitative measure equipment. 
  • OCXO is enclosed and covered with Dynamat Extreme Corporation (Made in USA) which is used to stabilize and minimize heat separation,  addition EMI material from KEMET EMI Shielding is placed on top of OCXO,  the outer layer is covered with real leather to isolate the heat factors for maximizing OCXO performance . 
  • Black Alu material + Carbon Fiber material front and backplate, solid anti-vibration. In addition, due to the thickness used, 3mm / 6mm Carbon Fiber material material with plate can provide solid EMI/ magnetic coverage.
  • Advanced instrument Symmetricom 5125A calibrated with plotted characteristics. The phase noise, and Allen Derivation defines different grades of the OCXO. 
  • Hand made in Hong Kong
  • 2 years warranty 
  • Internal R-Core LPS power supply included

    AfterDark. Black Modernize Internal LPS power supply 
    This device is designed to operate with internal R-Core Linear Power Supply designed for OCXO. This R-Core is extreme low ripple noise, made by copper and designed to enhance the dynamic and mid-range on Audio application. The electric transmission is further enhanced be Carbon Fiber back plate x Furutech NCF IEC Inlet. 

    Level selection value
    The OCXO installed in the product can calibrate the products used in industrial equipment for a long time, and use equipment with good characteristics. In order to optimally select the audio clock, we comprehensively evaluate with Symmetricom Flagship 5125A to analysis the phase noise characteristics and short-term stability (Allen dispersion) that can be determinate the OCXO grading accordingly.

    The OCXO installed in this product uses a stable OCXO unit that has been calibrated for several months. In order to make the best choice of OCXO. We are conducting a comprehensive evaluation of phase noise characteristics and short-term stability (Allen dispersion) during detailed inspection. 

    The final product will final measured and fine tuned with Keysight 53220A with reference to Atomic Clock , GPSDO. 


    Quality of OCXO is determined by Phase Noise at 1Hz / at 10Hz
    Phase noise: -119 to -113 dBc / Hz or lower at 1 Hz offset (Grades) -137 dBc / Hz or lower at 10 Hz offset
