Tools > S-match

          Serial match section. The window has a five main parts:

• Main menu.
• Groupbox Source.
• Groupbox Matching section.
• Groupbox Load.
• Control panel.

 

• File - common commands.
  • Save – save results in the file.
  • Print – print results.
  • Exit – close and return to main Tools window.
• Service
  • Calculator – On-screen calculator.
  • Change unit – for measurements of length:
    • Meter – meters.
    • Millimetre – millimetres.
    • Feet – feet.
    • Feet-Imper – Imperial system: feet and inch.
    • Inch – inch.
  • Line edit – enables the listed lines to be edited .
• Help - help.

 

This area displays the parameters of the source. 

• Rout – standard R.
• Frequency   – frequency.
• Power – power.
• VSWR – VSWR after the matching section included.

 

The load (antenna) parameters are displayed in this area.  Any antenna calculation performed  in the main window  will automatically  update the R and jX values shown here. 

• R – real part of the load impedance.
• JX – reactive part of the load impedance.
• Match loss – losses in the match unit. This window’s background colour changes if losses are high. 
• Power – power in the load.
• VSWR – VSWR of the load.
• Efficiency – of the match section. The Window’s  background colour  changes if the efficiency is low. 

 

Circuit the matching  unit with calculated values.

• This area displays the  matching section  serial line’s  C or L values.
• Type of line – drop down menu provides a selection of standard line impedances.
• Overlaid on the image are the calculated values of physical length and  electrical values of L or C ,and in the central area the  values of:
  • VSWR – measured at the beginning of the line.
  • Zin – input impedance, measured at the beginning of the line.
  • Loss – line loss, dB.
• Q drop down menu - sets quality factor of the inductor or capacitor.
• In the line Vs displays: voltage, current and complex (real + reactive parts) power in the L or C.
• The buttons 1 and 2 choose type of the serial element: L or C. 
• Option 1 is for a shorter line.
• Option 2 is for a longer line.

 

• Tune – button starts the calculation.
• Set as match – inserts calculated L or C series matching component  into model of the antenna in the main window. 
• Frequency plot – opens the frequency plot window.
