	VE Network Catcher (Lite)  License: Freeware
	Network Catcher, from Shunra Software, is a free network monitoring tool that records and displays latency and packet loss between your PC and any internet site. Use this freeware tool to monitor the quality of your network link. You can save all your recordings and send it to another user via email. Network Catcher also integrates with Shunra’s network simulation technology, enabling you to capture and import production conditions directly into network simulation scenarios and test applications under real-life network conditions. Network Catcher’s production network recordings are also ideal for baselining the performance of the production network, including best case, worst case and average application performance – giving you a great starting point from which to make informed decisions on performance limitations and expectations for new or existing applications that are about to be deployed over the network. Using production network parameters is ideal for testing applications when the target network already exists, such as a company’s corporate network or a customer’s network. However, if the target network has not yet been designed or built out, you can record a variety of different production networks and create a library of production network conditions which you can then use to test your applications and ensure that that they meet performance expectations in any potential network environment.

	Universal Software Oscilloscope Library  License: Freeware
	Real time universal oscilloscope GUI DLL library for data acquisition, modeling, simulation, debugging. Advantages:  1.Speedy performance: the library makes it possible to bring out into the beams of the viewing oscilloscope over a million quantization steps of signal per second – thus less than one micro-second is enough for one discreet.  2. Versatility. Convenient integration with any applied software: viewing oscilloscope is executed as a DLL exporting only 9 functions, of which 4 are usually enough to work with.  3. A good graphic interface: an instance of a viewing oscilloscope created by this library looks like a separate window, entirely independent of the program which activated it. This window contains all elements typical for a control panel of a real oscilloscope.  4. Convenient data export-import: data already realised in the oscilloscope beams can easily be transferred to other programs via clipboard (copy - paste) in textual form or via the saved text file. In such form data can be easily imported into most electronic table kinds of programs, as well as into programs of the Matlab type. The oscilloscope also allows to quickly load such data file into its beams.  5. Reliable and robust: this library employs only the most basic Windows API functions and reliably works in all versions of 32-bit Windows starting from the first 95 version. We tested and practically confirmed the possibility of relay of data to this oscilloscope directly from the computer’s hardware interrupt procedure (IRQ) and from any kind of anisochronous thread - which is important.  6. Future perspectives: the author is ready to consider business propositions concerning creation of specialised versions of this oscilloscope, including unique interface elements and functional changes needed by a prospective customer.

	Atanua  License: Freeware
	Atanua is a real-time logic simulator designed for educational use. It has an intuitive, OpenGL accelerated user interface, with which the user can place components and wires. Components include all common logic blocks, including gates, latches and flipflops. Additionally Atanua simulates about 30 different 74-series chips, as well as an 8051 microcontroller variant. Simulated and pure logic parts can be mixed in the same circuit. On the I/O front, Atanua includes several different frequency clock inputs, constant level inputs as well as buttons that are bound to the user's keyboard. LEDs in various colors as well as 7-segment displays are also included. There is also a simple logic probe for debugging. The simulated parts are designed to resemble their real-world counterparts, which is more attractive for the students than pure schematics. The students can practice lab experiments using the simulated chips. The simulation shows the signal state of each wire in real time. In addition to high and low signal level, parts may output "invalid" signal, stating that there is a problem with the circuit, such as outputs connected together, or missing wirings from some chip. Additional parts can be made using the plug-in interface. As an example plug-in, a driver for the Velleman K8055 USB experiment board is provided, with which the user can mix simulated and real-world components. An anti-cheating tool is also available for teachers who wish to use Atanua for homework. Author: Jari Komppa| Date: 27-03-2008 | Size: 1598 KB
