Spectrum visualization with Fosphor

Description

This tutorial illustrates use of RFNoC Fosphor block for spectrum visualization. RFNoC Fosphor block is the FPGA accelerated version of 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].

Running a GRC application on a testbed node requires using graphical user interface(GUI) over SSH. This tutorial also illustrates use of MobaXterm and jumphost to setup X forwarding for accessing GUI over SSH.
