TxPlan

TxPlan is a tool intended for the use of professionals, who are involved with the planning of radio and satellite communications systems. TxPlan can be used to illustrate the layout of transponders on a satellite, or the layout of carriers within a frequency band. The program also allows the user to manipulate the carrier frequencies, for example squeezing them closer together to minimize satellite lease bandwidth, or illustrating the effect of passing them through a frequency converter. It will also calculate and report the frequencies of third order intermodulation products resulting from non-linear devices or PIMs. TxPlan deals only with modern digitally modulated carriers. Analogue AM or FM modulated signals are beyond the scope of this program.

Features include edit the title of the diagram via the View Options menu, change the view frequencies, to zoom in on a subset of carriers, or zoom out, choose whether to label carrier edge frequencies, or only the centre frequencies, save the displayed diagram to a bitmap image file, and comprehensive help topics included on all features of the program.
