== Using Sivers mmWave equipment on COSMOS SandBox1 == === Description === A pair of Sivers EVK06002s, evaluation kits for Sivers IMA TRX BF/01, are deployed on COSMOS SandBox1. TRX BF/01 is a 16+16 IEEE802.11ad Beamforming Transceiver with a complete Radio front-end with 57-66 GHz mmWave frequency range. Current mmWave setup in COSMOS SB1 looks as shown in the figure below. || [[Image(mmWaveSB1_withSW.jpg, 500px)]] || Baseband data samples to Sivers front-ends are fed by USRP X310s with BasicTX and BasicRX daughtercards. BasicTX (https://www.ettus.com/all-products/basictx/) daughtercard is a simple wideband (250MHz) interface to the raw DAC signals from USRP. Similarly BasicRX (https://www.ettus.com/all-products/basicrx/) provides a simple, wideband interface to USRP ADCs. The raw data can be generated/processed in the FPGA on USRP X310 and can be transferred to the host servers srv1-lg1, srv2-lg1 over 10G Ethernet link for further processing/storage. Control software for Sivers front-ends runs on srv3-lg1 and srv4-lg1. srv3-lg1 is directly connected to Sivers SN0243 and srv4-lg1 is connected to Sivers SN0240. These servers also have a direct USB connection to the X310s, for JTAG programming. This tutorial demonstrates how to transmit and receive a signal in the 60GHz mmWave spectrum using these Sivers front-ends. === Prerequisites === In order to access the test bed, create a reservation and have it approved by the reservation service. Access to the resources is granted after the reservation is confirmed. Please follow the process shown on [wiki:cosmos_workflow the COSMOS work flow page] to get started. === Resources required === 4 servers srv1-lg1 to srv4-lg1, 2 USRP X310s sdr2-md2, sdr2-md3 and both the Sivers platforms on COSMOS SB1. === Execution === ==== Prepare the host nodes ==== The image sivers_sb1_cosmos.ndz, has UHD and Sivers control software installed. * Load sivers_sb1_cosmos.ndz on srv3,srv4 {{{ prasanthi@console:~$ omf load -i sivers_sb1_cosmos.ndz -t srv3-lg1,srv4-lg1 }}} * If using an example application from UHD, sivers_sb1_cosmos.ndz can be used on srv1 and srv2 as well. If using a custom UHD application or Gnuradio application, please load baseline_sdr_1804.ndz. {{{ prasanthi@console:~$ omf load -i sivers_sb1_cosmos.ndz -t srv1-lg1,srv2-lg1 }}} {{{ prasanthi@console:~$ omf load -i baseline_sdr_1804.ndz -t srv1-lg1,srv2-lg1 }}} * Turn the nodes on {{{ prasanthi@console:~$ omf tell -a on -t srv1-lg1,srv2-lg1,srv3-lg1,srv4-lg1 }}} * Check the status {{{ prasanthi@console:~$ omf stat -t all }}} {{{ ----------------------------------------------- Node: mob2-1.sb1.cosmos-lab.org State: POWERON Node: mob3-1.sb1.cosmos-lab.org State: POWERON Node: sdr2-lg1.sb1.cosmos-lab.org State: POWERON Node: sdr2-md1.sb1.cosmos-lab.org State: POWERON Node: sdr2-md2.sb1.cosmos-lab.org State: POWERON Node: sdr2-md3.sb1.cosmos-lab.org State: POWERON Node: srv1-lg1.sb1.cosmos-lab.org State: POWERON Node: srv2-lg1.sb1.cosmos-lab.org State: POWERON Node: srv3-lg1.sb1.cosmos-lab.org State: POWERON Node: srv4-lg1.sb1.cosmos-lab.org State: POWERON ----------------------------------------------- }}} * ssh to the nodes, use option -Y if using GUI. * The IP addresses for Ethernet Port 1(10G) on the X310s sdr2-md2 and sdr2-md3 were hard-coded to 10.115.2.2 and 10.115.2.3 respectively.
