     3= Service: RF Control =
     4
     5This service is used to configure the RF front ends of the nodes. The functionality follows the descriptions on the [wiki:hardware/rf-front-end RF front end] page (eg. setting the filters for one TX chain applies the setting to both TX chains of the node).
     6
     7== Usage ==
     8
     9All the available methods are accessible from the a testbed console via an HTTP API located at {{{am1.cosmos-lab.org:5054/rf_control}}}. This API can be interacted with via a command line tool such as "curl" or any script using a "REST client" library.
     10
     11=== Get the current configuration ===
     12
     13This API call is used to get the current configuration of the RF front end(s) with respect to a node or list of nodes. The response will specify the parameters of the TX chain for the node(s) in question. It will show for a given node's {{{rf_port}}}, what {{{antenna}}} would be used if it were {{{connected}}}, whether the power amplifier ({{{power_amp}}}) is on or off, and the lower frequency ({{{f_lower}}}) and upper frequency ({{{f_upper}}}) of the filters.

     62=== Turn off power amplifiers ===
     63
     64This API call is simply a shorthand to easily turn off the power amplifiers for a given node. Keep in mind that power amplifier state is shared between nodes in the same physical location (eg. sdr1-md1.bed.cosmos-lab.org and sdr2-md1.bed.cosmos-lab.org).
