Definitions Of The Switching Modes

There are currently seven pre-defined states for the switch_mode GO Keyword. switch_mode also has four more user defined states and five modes which have not yet been implemented.

The states are¹²:

Total Power; NONE; TPWCAL

   
${\rm number\_of\_phases = 2}$
${\rm switchDeltas = [ 0.0 ]}$
${\rm beam\_ctrl = \lq\lq manual''}$
${\rm cal\_ctrl = \lq\lq external''}$
${\rm pol\_ctrl = \lq\lq manual''}$
