    4  A pair of Sivers EVK06002, 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 and it covers 57-66GHz.

    66Current deployment of COSMOS SB1 consists of 4 servers, 2 USRP N310s, 2 USRP 2974s and mmWave equipment, as shown in the following figure.  Nodes, srv1-lg1 and srv2-lg1 are directly connected (over USB, for JTAG programming) to USRP X310s sdr2-md2 and sdr2-md3 respectively. srv1-lg1 and srv2-lg1 also control the Sivers evaluation kits over USB.

    10 This tutorial demonstrates how to use the RFNoC channel sounder design for obtaining the PDP of channels up to 100MHz wide. An FPGA correlator module computes real time correlation power, and an averaging module, averages contiguous sets of PDP over time, and sends the result to host CPU. This design is compatible with 3rd generation Ettus USRP devices. This tutorial uses USRP X310s on ORBIT grid.
     10This tutorial demonstrates how  to transmit and receive a signal using  a pair of Sivers 60GHz evaluation kits on COSMOS SB1.

    16 2 host nodes and 2 USRP X310s are required for this experiment. USRP X310 devices in ORBIT grid are located in the massive MIMO mini-racks [https://www.orbit-lab.org/wiki/Hardware/bDomains/aGrid#Massive-MIMOmini-racks].
     164 servers srv1-lg1 to srv4-lg1, 2 USRP X310s, sdr2-md2, sdr2-md3 and both the Sivers platforms on COSMOS SB1.

    2020==== Prepare the host nodes ====
    2121
    22  Determine the set of nodes that you're using. If you have a topology assigned, it will be entered in the form "system:topo:group-red" for example.
    23 * Load channel-sounder.ndz on a pair of nodes (group assigned to you) 
     22 As shown in the figure above, Sivers control software runs on srv3,srv4, whereas the UHD/gnuradio application to generate/process data samples runs on srv1,srv2. So, appropriate images have to loaded on these servers.
     23 The image sivers_sb1_cosmos.ndz, has UHD and Sivers control software installed.
     24* Load sivers_sb1_cosmos.ndz on srv3,srv4
    2425  {{{
    25   prasanthi@console.grid:~$ omf load -i channel-sounder.ndz -t system:topo:group-red
     26  prasanthi@console:~$ omf load -i sivers_sb1_cosmos.ndz -t srv3-lg1,srv4-lg1
    2627  }}}
    27 
     28* 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.
     29  {{{
     30  prasanthi@console:~$ omf load -i sivers_sb1_cosmos.ndz -t srv1-lg1,srv2-lg1

    3239
    3340* Check the status

    98   If you see the above at the end of uhd_usrp_probe output, the USRPs are ready. Spreader_0 is used to spread the transmit signal, and Corrmag63avg8k_0 is the correlator on the receive side.
