OctoClock-G for fully integrated system with internal 10 MHz/PPS source. Can you please combine both UHD Sinks? Just increase the number of motherboards and channels to 2 and copy the MIMO attached USRP's settings into channel 2. This board is directly connected to the clock distributor (Octoclock-G) with the aim of splitting the same reference clock to all the boards. The upgraded OctoClock-G includes a high-accuracy, internal GPS-disciplined oscillator and does not require external signals to be supplied. a single Gigabit Ethernet The OctoClock serves as an 8-way PPS USRP X300 and X310 Configuration Guide. Nr. For measurement purposes, a vector signal transceiver (VST) is included in the system ad it is usually used as a real-time Spectrum Analyzer. The Octoclock takes up the same space as two USRPs would in a rack. Middle: The White Rabbit clock distribution unit, which distributes clocks via ethernet cables. In available MIMO examples (e. m. The OctoClock accepts 10 MHz and PPS signals from an external source, and distributed each signal 8 ways. This is the perfect setup. This can be used to build multi-channel systems that are synchronized to a common timing source. com To subscribe or unsubscribe via the World Wide Web, visit http://lists. 8d). If you want to hack some quickly for a few USRPs, use a T-piece for the PPS and a splitter for the 10 MHz, you'll be fine. DAC-voltage etc. g. This could be as simple as Telnet. Lund University / EITF20/ Liang Liu 2015 octoclock_firmware_burner(1) - OctoClock Firmware Burner OCTOPUS(1) - Ab-initio Time-dependent Electronic Structure. In addition, with the OctoClock-G, NMEA strings may be obtained from the internal GPSDO via the UHD API. The PXIe 8880 includes two 10/100/1000BASE TX (Gigabit) Ethernet ports, two USB 3. ettus. You do not need Ethernet connected to the Octoclock, so that's ok. 双SPF+端口(1 Gigabit Ethernet, 10 Gigabit Ethernet, Aurora) 支持外接Clock reference 和PPS time reference.
