    55This subsystem consists of a central arbitrary waveform generator (Agilent ESG) connected to four distribution antennas through a RF switch.
    6 Using this subsystem, users can inject ''individually'' controllable (power/frequency) noise into the ORBIT grid.

    56 To set AWGN on channel 36 at -30 dBm on antenna1 use
     51To set AWGN on channel 36 at -30 dBm on antenna1 use the following commands (either through a browser or '''wget''')
     52 * Step 1: Select AWGN bandwidth (channel bw for 802.11a/b/g is 20 Mhz)
     53    * {{{
     54          wget http://instrument1.orbit-lab.org/awgn?bandwidth=20
     55      }}}
     56 * Step 2: Set power level to -30 dBm
     57    * {{{
     58          wget http://instrument1.orbit-lab.org/set?power=-30
     59      }}}
     60 * Step 3: Set channel number to 36
     61    * {{{
     62          wget http://instrument1.orbit-lab.org/set?bchannel=36
     63      }}}
     64 * Step 4: Start RF injection
     65    * {{{
     66          wget http://instrument1.orbit-lab.org/start
     67      }}}
