= antenna: Configure Noise Insertation and Spectrum Measurements =

This command allows the experimenter to inject noise into the grid through the available antennas. While currently not supported, the same command will also provide access to spectrum analyzers.


== Syntax ==

'''antenna(''selector'').signal.''resource'' = ''value'''''[[BR]]
'''antenna(''selector'').signal {}'''

  * '''selector''': Expression to select the antenna set.
  * '''signal''': Path to noise generator.
  * '''resource:''' Name of resource.
  * '''value:''' Value to assign to resource.

The supported syntax for the ''selector'' can be found in [wiki:Documentation/NodeHandler/Commands/defNodes defNodes].

The current resources for the signal generator are:

  * '''bandwidth''': Bandwidth of signal
  * '''channel''': 802.11 channel
  * '''power''': Output power in dbM ???
  * '''on''': On when set to true, off when set to false

The locations of the antennas within the grid can be found '''missing'''.

== Usage ==

{{{
antenna(4,4).signal {|s|
  s.bandwidth = 20
  s.channel = 36
  s.power = prop.noisePower
}
}}}
