Probe 4 - Propagation Software for Communications, DTV, FM, LPTV

Probe gives you the ability to be an expert at predicting radio propagation in the 20 to 20,000 MHz frequency range. Now Probe 4 offers more powerful features, flexibility and speed, including the ability to take advantage of multiple program threads and dual core or quad core processors.

Probe is designed to be as flexible as possible to accommodate the various requirements of propagation analysis for multiple communication services. From 800 MHz two-way communication performance to the the FCC's DTV interference rules, Probe is the choice as the universal propagation prediction tool.

Critical to Probe's success is its professionally integrated, world wide, geographic mapping engine which combines the best polygon mapping graphics available with precision coordinate information and map projections. Probe produces absolutely stunning maps with appearances that rival even the best of the traditional atlas map makers. All background colors, highway colors and road markers, city names, river line-thickness, lake and ocean colors and label font names and sizes are fully user-selectable. You can configure every aspect of Probe's maps right down to the street level to make them look perfect to the intended reader. The program contains a complete set of editing and drawing for adding text, pointer arrows, circles, squares, lines and other information to the maps.

Probe's what-you-see-is-what-you-get interface provides you with a screen view of the exact printed output. The program builds in a mouse-zoom feature which enables the you to enlarge any rectangle you select on the map to full screen so that the selected area can be examined in detail or printed. Maps, scaled selected to your choice, can be sent to color or black and white printers or can be internally converted to graphic files.

Probe 4 offers a polygon drawing tool that allows the user to enhance maps by highlighting certain areas. When the tool is used in the polygon mode, users can form a shape on the screen with the mouse and Probe will calculate the population and area within the shape. This tool is particularly useful for calculating the population and areas of odd contour overlaps or interference area shapes.

Single or multiple station communications or broadcast coverage studies, incoming or outgoing interference studies, highest signal two-way coverage are all available for user selection. For broadcast related interference studies, Probe automatically identifies the stations to which interference is caused, as well as those stations which cause interference to the user's reference station facilities.

Probe uses any of the numerous V-Soft Communication's terrain elevation databases. (Databases of 3 arc-seconds are available from V-Soft Communications for Canada, USA, Mexico, Caribbean, Central America and South America, Europe, Asia, Australia and New Zealand.) Thirty arc-seconds resolution terrain databases are also available for anywhere in the World. In addition to the Longley-Rice (TECH-NOTE 101) methods, Probe also uses the ITU-R Model, the Federal Communication's Commission "FCC" propagation model, the Okumura/Hata/Davidson and Cost-231/Hata propagation models as well as the FCC's proposed PTP (Point-to-point) methods, versions one and two. (The PTP method, authored by the FCC's Harry Wong, is primarily based on Fresnel clearance.) Terrain Integrated Rough Earth Model (TIREM) methodology is available as an option.

For DTV analysis, Probe's optional DTV OET-69 module calculates the population and area of broadcast TV interference using the precise method prescribed by the FCC.
