linSmith: Screenshots (and a 'papershot')

Main window, three main pages

The main program, shown with a simple example problem. The right panel is shown in the 'loads'-mode, with 5 frequencies and the corresponding load impedances defined. (The example was taken from 'ARRL Antenna Impedance Matching').

The right panel is on the 'elements'-page, showing the two components used to adapt the loads to a fairly good result.

On the 'Log'-page, we can observe the numerical results after each component.


The first configuration page has a few general options, like, eg. enabling or disabling the SWR circle and defining its diameter.

The second page defines how to render the chart background: its size, and offsets in x and y direction.

The next page permits defining the characteristics of the Postscript output.

The 'Impendances' page defines the appearance of the impedance marks for both the screen and print output.

The 'Connections' tab defines the appearance of the connecting lines on the chart: constant-R, -G, and transmission lines.

Recently added is the 'Remote' tab, where parameters for the remote control of linSmith can be set. Instruments can send their measurements to the program automatically.

The 'Noise bridge' page permits selection of the noise bridge type, and the fixed components, such as the parallel capacitor.

finally, the 'Files' page shows the last data and circuit files selected, and permits the selection of the serial port for data adquisition.

Print output

An example of a rather complex chart printed on a simple inkjet printer.
