This application note describes the use of integrated GPS-disciplined oscillators (GPSDOs) for the USRP N-Series and E1xx. dependent on selected interface and host-PC performance. The internal VITA timestamp will be initialized to the GPS time, and the internal oscillator will be phase-locked to the 10 MHz GPSDO reference. A GPSDO locked to the GPS constellation can provide time synchronization within 50 ns of the global GPS standard and very high clock accuracy. 3 Installation Guide; 2 GPSDO (OCXO) 2. 3VDC CMOS RS-232 Control NMEA & SCPI-99 Control Commands, Integrated into UHD GPS Frequency L1, C/A 1574MHz GPS Antenna Active (5V compatible) or Passive USRP must be configured with Board-Mounted GPSDO (OCXO) or Board-Mounted GPSDO (TCXO). These provide a high-accuracy XO, which can be disciplined to the global GPS standard. 04. Note that this does not enable the synchronization of multiple devices. Figure 2 - GPSDO MIMO Capability of Ettus Research USRP Devices The GPSDO will function as a reference even when there is no GPS reception. 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. Keep in mind that the two sides of the GPSDO have a different number of pins. Obtaining the correct SDK If you have purchased an internal GPSDO, follow the instructions on Internal GPSDO Application Notes (USRP-X3x0 Models) to insert the GPSDO. pdf (0 × 0 pixels, file size: 324 KB, MIME type: application/pdf) File history Click on a date/time to view the file as it appeared at that time. May 16, 2016 · Recommended Internal GPSDO for Each Device. When turning on the USRP B2X0 device, a green LED should illuminate on the GPSDO. Approved Optics BN-CKM-SP-SR-A; Known-Good Cables The USRP N310 is a networked software defined radio that provides reliability and fault-tolerance for deployment in large-scale and distributed wireless systems. Obtaining the correct SDK USRP N300; DC Power Supply (12V, 7A) 1 RJ45 – SFP+ Adapter; 1 Gigabit Ethernet Cat-5e Cable (3m) USB-A to Micro USB-B Cable (1m) Getting Started Guide The B200 and B210 cannot support an external 10 MHz reference if a GPSDO is already present on the motherboard. The USRP™ Hardware Driver Repository. Ettus Research specializes in software defined radio (SDR) systems. For information regarding the GPSDO that is compatible with the USRP X-Series, please see: Internal GPSDO Application Notes (USRP-X3x0 Models) Jan 8, 2013 · This SDK contains a cross-compiler, a cross-linker as well as a cross-debugger and can be used to develop your user space applications for the Ettus USRP-E310 devices. 3 Certificate of Volatility; 3 GPSDO (TCXO) 3. zir jfirt wneaa bqnzu tomswf hryzjvh tiisk wuo pfnl smdooau
