  • Board Mounted GPSDO (TCXO) Recommended for USRP B200/B210

    783454-01 | BOARD MOUNTED GPSDO KIT (PCB-MOUNTED GPS-DISCIPLINED TCXO)  $ 1,362.00 USD

    This is a GPS-disciplined, temperature-controlled crystal oscillator (GPSDO), which is recommended for use with a USRP B200/B210.  The GPSDO provides a high-accuracy 10 MHz reference and 1 PPS signal, which allows developers to build systems that serve applications with improved frequency accuracy (75 ppb in unlocked condition) or global timing alignment (50 ns in locked condition).

    Overview

    This is a GPS-disciplined, temperature-controlled crystal oscillator (GPSDO), which is recommended for use with a USRP B200/B210.  The GPSDO provides a high-accuracy 10 MHz reference and 1 PPS signal, which allows developers to build systems that serve applications with improved frequency accuracy (75 ppb in unlocked condition) or global timing alignment (50 ns in locked condition).

    Unlike the OCXO-based version, which is recommended for use with the USRP X300/X310, this lower power module can be used with the USRP B200/B210 in a USB bus-powered configuration. 

    We recommend reading the GPSDO Selection Guide to ensure this is the right device for your application.

  • 用于 USRP B200/B210 的板载 GPSDO (TCXO)

    简介

    板载 GPSDO 套件(PCB 板载 GPS 校准 TCXO)

    这是一款 GPS 校准的温控晶体振荡器 (GPSDO),建议与 USRP B200/B210 配合使用。GPSDO 提供高精度 10 MHz 参考频率和 1 PPS 信号,使开发人员能够构建具有更高频率精度(解锁条件下 75 ppb)或全局时序校准(锁定条件下 50 ns)的应用系统。

    这是一款 GPS 驯服温控晶振模块(GPSDO),推荐用于 USRP B200/B210 系列设备。该模块可输出高精度的 10 MHz 参考频率和 1 PPS 时间信号,使开发者能够构建具备更高频率精度(在未锁定状态下达 75 ppb)或全球时间对齐能力(在锁定状态下精度约 ±50 ns)的系统。

    与基于 OCXO 的版本不同(该版本更适用于 USRP X300/X310),此款 GPSDO 模块功耗较低,可在 USB 总线供电条件下直接与 USRP B200/B210 配合使用,无需外部电源。
