    7 This tutorial illustrates use of [https://archive.fosdem.org/2015/schedule/event/rfnocfosphor/attachments/slides/804/export/events/attachments/rfnocfosphor/slides/804/fosdem2015_rfnoc_fosphor.pdf RFNoC Fosphor block for spectrum visualization]. RFNoC Fosphor block is the FPGA accelerated version of [https://projects.osmocom.org/projects/sdr/wiki/Fosphor gr-fosphor (CPU/GPU version)]. As any other RFNoC blocks, RFNoC Fosphor can be instantiated on 3rd generation USRP devices, and can be used in conjunction with gnuradio-companion(GRC) on the host computer. This tutorial demonstrates GRC RFNoC Fosphor application on USRP-2974s in [COSMOS testbed wiki:Hardware/sdr/usrp2974] and USRP X310s in [ORBIT].

    99Running a GRC application on a testbed node requires using graphical user interface(GUI) over SSH. This tutorial also illustrates use of [https://mobaxterm.mobatek.net/ MobaXterm] and jumphost to setup X forwarding for accessing GUI over SSH.

     21 1. [wiki:/GettingStarted#LogintoyourReservation Login] into sandbox 1 console (console.sb1.cosmos-lab.org) with an SSH session. SSH session for COSMOS SB1 with MobaXterm can be setup as shown, with remote host = console.sb1.cosmos-lab.org, and username = your COSMOS username. X11 forwarding is enabled to access GUI.

     38 1. Log into the SDR with -Y for X11 forwarding
     39{{{#!shell
     40ssh root@sdr2-s1-lg1 -Y
     41}}}
     42Another way is to setup a MobaXterm session to access the SDR, with console as the jumphost.
