GPSDO for USRP X Series
GPSDO for USRP X Series (PCB-Mounted GPS-Disciplined OCXO)
This is a GPS-disciplined, oven-controlled crystal oscillator (GPSDO), which is compatible with a USRP X300 or X310. It can also be used with the USRP B200/B210, but the system will require external power. The GPSDO provides a high-accuracy 10 MHz reference and 1 PPS signal, which allow developers to build systems that serve applications with improved frequency accuracy and global timing alignment.
What's Included
- Board-Mounted GPSDO (OCXO)
- Documentation for Installation and Configuration/Setup
Recommended for use with:
- A USRP X300 and USRP X310 for a high-accuracy clock reference
- Add a GPSDO Mini GPS Antenna to synchronize the GPSDO to the GPS constellation for 25 ppb frequency accuracy and 50 ns alignment across the globe
