Experiment with transmission lines. Watch impedance points change on a Smith chart as you quickly vary input parameters using spin buttons. Plot matched line loss versus frequency.

Transmission Line Details shows the impedance and SWR (or rho) at both ends of a transmission line and the details of power loss in the line. In addition to numeric results, impedance points are shown on a Smith chart and loss components are shown on bar charts. Includes characteristics for 49 built-in line types. You can modify these values to see how small changes affect the results or to specify custom lines. All program inputs may be changed directly or you can use spin buttons to make the changes. If you are using a moderately fast computer you can hold down a spinner and "watch the movie" on the charts as the results are recomputed.

Transmission Line Details runs as a stand-alone program. However, it makes use of certain components that are found in all Microsoft Office applications such as Word, Excel, Access, etc. If you have not installed any MS Office programs (97 or later) you will see an error message concerning "FM20.DLL" when attempting to run TLDetails. See www.ac6la.com/tldetails.html (bottom of page) for more information.

TLDetails must be run with a screen size of 800x600 or greater, 640x480 is not supported.
