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.
