TransTenna Pro Software


TransTenna Pro is impedance transformation software for use with transmission lines. It may be used in conjunction with an impedance measuring instrument such as an SWR analyzer, RF bridge, network analyzer or vector voltmeter. The program performs impedance transformation calculations on a transmission line and this allows the operator to measure the impedance at one end of a transmission line and then calculate the impedance at the other end of the transmission line. It can transform the measured impedance in either direction, that is, from the antenna/load end of the transmission line to the receiver/transmitter end of the transmission line or vice versa.

The calculated results data is provided in both series and parallel formats and takes into account the transmission line characteristics including length, velocity factor, characteristic impedance and cable loss. Other data is also supplied and includes SWR, return loss, transmission line loss and transmission line length in lambda.

TransTenna Pro is not limited in use to any specific instrument and may be used with any type of equipment capable of providing the series equivalent resistance and reactance ( R and X ) measurement data. A calculator is also provided for use with instruments which give only Impedance and SWR measurement data and the program supports selected RF bridges and vector voltmeter input.

A cable data base is provided which allows the operator to retrieve data for a specific transmission line and automatically enter that data into the main worksheet. An additional feature provides automatic calculation of transmission line loss at the operating frequency. The data base can be edited to add, change or remove transmission line entries.

A series of specialized tools are provided to enhance the usefulness of the program and to make other calculations for the operator.

The program supports printing of the main worksheet to provide a permanent record of the data entry and calculated results. The Windows system printer is used and both graphics and textual printing are supported.

TransTenna Pro uses the general transmission line equations and its accuracy is limited only by the accuracy of the data entered by the operator. In effect, TransTenna Pro provides an easy to use alternative to the Smith Chart for transmission line analysis.
