Tools > Q-match

          Q-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 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 – active power in the load.
• VSWR – VSWR of the load.
• Efficiency – of the matching 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.
• The matching line types are selected from the two drop down menus in Line 1 & Line 2.
• The displays shows the calculated values for each line (physical length & length in wavelengths).
• Overlaid on the image are the electrical values of the two line are displayed.
  • VSWR – VSWR, measured at the beginning of the line.
  • Zin – input impedance, measured at the beginning of the line.
  • Loss – line loss, dB.

 

• Tune – starts calculation.
• Set as match – – inserts calculated the LC matching section into model of the antenna in the main window.
• Frequency plot – opens the frequency plot window.
