If you've ever needed to test digital signals, then this could be the kind of tool that appeals to you. If you've got no idea how to test digital signals, or any need to, then it will be of no use to you at all.

WinIQSIM is a laboratory environment with all the necessary tools for the analysis and evaluation of digital transmission systems. You can simulate all systems involved in the process of modulation and reception of signals. The program does this by allowing you to define blocks of data sources, configure them and even simulate signal distortion or interference. The instructions are extremely hard to follow though for the none initiated. The developers advise you that "The signals generated with the aid of the R&S® WinIQSIM™ software can be output by the integrated solution in the R&S® SMU (option R&S® SMU-B10) and the R&S® SMIQ (option R&S® SMIQB60) as well as the Arbitrary Waveform Generator R&S® AMIQ. R&S® WinIQSIM™ is provided with these three arbitrary waveform generators free of charge." Therefore, it's worth reiterating that this is only designed for those that know specifically what they are doing with digital wave signals.

Seems like a highly complex and useful program in the right hands but none scientists need not apply.

RadioWorks is a program that lets you save the tedious and, in some cases, complex calculations needed to design or evaluate the performance of a terrestrial antenna.

With RadioWorks, you can calculate the length of the antenna depending on it's frequency and wavelength. You can also calculate the loss of the signal according to the receiver model and power according to parameters such as distance, the type of terrain or obstacles to cover. The program intelligently utilizes tabs for different fields being tested so you can easily keep track of what you're looking at. You can also see how the program will react under different conditions Use the Distance and Power change prediction calculator to predict how a proposed transmitter such as increasing or a decreasing the power. If you're not a maths whizz, which I'm certainly not, all the mathematical formulas used by the application are on display which can be rather confusing although they are accompanies by explanations and usage information.

if you're setting up a radio system in a studio or house then this program may be of use but all others should stay away as it's rather complicated.

FindGraph is a comprehensive, feature-rich graphing, digitizing and curve fitting software specially created for these purposes. Take any graph or data from any source (Web or PDF document, for example) add your comments and perform any manipulations, like nonlinear regression or curve fitting. Then print your results or export them to Excel or other database.

Data can be entered:

• By importing it from ASCII files
• By cutting and pasting it from other Windows based applications (Excel spreadsheets)
• By digitizing screen charts
• By typing it into a standard spreadsheet interface

Supported graph types are:

• Scatter diagrams and line graphs
• Points density distributions
• Points groups diagrams

You can specify the unlimited number of points and lines. Their graphs will be plotted in one coordinate system, allowing comparison of empirical and analytical data. Lots of graph and coordinate plane parameters. FindGraph is COM server. This means that plots can be copied and pasted (embedded) directly into word processors, Excel or drawing programs. The program supports OLE automation and can be built-in to user software. Examples (MS VB, MS VC++) are included. Methods and properties are documented. FindGraph allows you to export information to the other programs and files. Points can be saved to ASCII tables. Regressiion lines, curves, points and commentaries can be saved to XML file.

The RPN Engineering Calculator is a Windows program that performs the functions of a Reverse Polish Notation scientific calculator (an RPN calculator) and a lot more. It offers more than 250 solutions and many conversions with six unique keypads: Standard, Engineering, Binary, Magnetics, Trigonometry, and Convert, (click on the individual keypad name for a complete description of that keypad). It's even easier to solve the more complex functions; fourteen of them are now individual calculators that solve those functions only!

WinADV provides an integrated environment for viewing, reviewing, and processing data collected using SonTek and Nortek acoustic Doppler velocimeters (ADV's). WinADV was written for Windows 95/NT, using Visual Basic 4.0.

WinADV permits easy, visual review of ADV data files in the office following data collection. It simplifies filtering of data and aids in the identification of anomalies caused by low signal strength or overranging of the ADV probe.

It also simplifies the processing of data collected using flag markers, and permits various schemes for the use of flag markers during data collection.

In summary, WinADV minimizes the need for manipulating and analyzing large quantities of time series data

RAW Materials is an effective tool which calculates lots of different material parameters (weights, lengths, surface area and price) in the most common market shapes (sheets/plates, round tubes, square tubes, round bars, “T” profiles and “L” profiles).

The prices are shown by mtr, sq. mtr. or Kg. and in three different currency (EURO, US DOLLAR and POUND STERLING). You can, of course, chose and change both the exchange rates and densities of the materials.

RAW MATERIALS 3.0 is the definitive tool for people who work with raw materials in their companies.
