Creating the Lua Settings File

Specify the loading and excitations for each port using a Lua settings file.

1. Open a text editor and create the following settings file:

   -- Non-active port configuration 
   nonActivePortsConfiguration = {}
   nonActivePortsConfiguration.Data = {}
   -- Empty non-Active port configuration since all ports are active.
   
   -- Active port configuration  
   activePortsConfiguration = {}
   activePortsConfiguration.Load ={}
   activePortsConfiguration.Load.Data ={}
   -- Source Port1 source = {}
   source.Label = "Port1"
   source.Index = 1
   source.Value = pf.Complex(1,0)
   table.insert(activePortsConfiguration,source)
   -- Load attached to active port 1
   -- Type = 1 (direct connection),
   -- Type = 2 (complex), 
   -- Type = 3 (one port Touchstone network), 
   -- Type = 4 (two port Touchstone network)
   load ={}
   load.Type = 2 
   load.Value = pf.Complex(10,-30)
   table.insert(activePortsConfiguration.Load.Data,load)
   -- Source for Port2  
   source = {}
   source.Label = "Port2"
   source.Index = 2
   source.Value = pf.Complex(1,0)
   table.insert(activePortsConfiguration,source)
   -- Load attached to active port 2
   load ={}
   load.Type = 2
   load.Value = pf.Complex(70,-30)
   table.insert(activePortsConfiguration.Load.Data,load)
   -- Source Port3
   source = {}
   source.Label = "Port3"
   source.Index = 3
   source.Value = pf.Complex(1,0)
   table.insert(activePortsConfiguration,source)
   -- Load attached to active port 3
   load ={}
   load.Type = 2
   load.Value = pf.Complex(105,-30)
   table.insert(activePortsConfiguration.Load.Data,load)
   -- Source Port4
   source = {}
   source.Label = "Port4"
   source.Index = 4
   source.Value = pf.Complex(1,0)
   table.insert(activePortsConfiguration,source)
   -- Load attached to active port 4
   load ={}
   load.Type = 2 
   load.Value = pf.Complex(50,0)
   table.insert(activePortsConfiguration.Load.Data,load)
   -- Return the configurations in a settings table
   return {activePortsConfiguration, nonactivePortsConfiguration}
   

2. Save the example3_settings.lua file.
