SoftWright announces the next version of its software, HDSpectrum. Users of the Terrain Analysis Package can view transmitted and received frequency spectrum in the graphical form of a spectrum analyzer . SoftWright's tool allows the engineer to examine the resultant potential hit frequencies in many ways. With HDSpectrum, intermodulation products can be analyzed as well as the participating frequencies. It can properly consider broadcast, simplex, half-duplex, and full-duplex facilities. The software can also take into account the deviation of the transmitted frequencies as well as user-specified bandwidth around a protected or received frequency.
