描述

Fury GPSDO通过在一个低成本模块中结合极高的GPS定时性能和最新的OCXO技术,提供了超高的频率精度。Fury作为一种非常高的性能、低相位噪声、低ADEV噪声和非常高的保持性能参考是非常有用的。Fury在实验室条件下提供1PPS、各种10MHz和NMEA输出的效果非常好,DOCXO变体在拒绝GNSS的环境中或在没有GNSS信号的长时间内提供了卓越的保持漂移能力。

特点

  • 无需校准
  • 提供比铷钟参考更高的稳定性
  • 测量间隔大于1秒时,Allan方差可能小于1E-011
  • 标准相位噪声在>10Hz偏移时小于125dBc
  • 功耗小于5W,工作电压11V到14V,支持电池供电
  • 自2019年,Fury GNSS接收机升级为JLT M12M接收机,支持GPS/Globass/Gileo/BeiDou和QZSS
  • 具有老化和温度补偿的保持模式
  • 告警输出
  • 可通过使用LCD和键盘进行控制,或通过使用标准SCPI命令的RS-232控制进行控制。设置自动存储在非易失性存储器中
  • 正弦波和CMOS输出是标准配置
  • GPSCon Windows图形化软件和SNTP服务器软件兼容
  • 可作为OEM模块或铝制外壳封装提供
  • Fury可根据稳定性/成本要求订购2种不同的选项:
  • 单 OCXO。具备非常好性价比。
  • 双 OCXO。具备更高的稳定度和更好的保持性能。
