Osqoop is an open source software oscilloscope. It features an arbitrary number of channels and long acquisition durations. Signal processing and external peripherals control is possible through a plugin architecture. Data sources are plugins as well. Osqoop is easy to learn thanks to an ergonomic user interface. For the power user, keyboard shortcuts allow fast and effective interactions. Osqoop allows us to test several digital signal processing algorithms, varying their parameters and observing the result in real-time.Osqoop provides the following features:

• Arbitrary number of channels and acquisition durations (required memory = nbChannels * nbSamples * 2);
• Data sources as plugins: externals or software, examples and writing guide provided;
• Signal processing through plugins: control of external hardware possible, examples and writing guide provided, save and load of plugins configurations;
• Modular architecture, documented C++ code;
• Trigger support: simple, automatic, none, up slope, down slope and both;
• Rich display: points or lines, zoom on part of the signal, instant freeze on key press, permanent mode with progressive fadeout.
• Export to txt or pdf format.

Osqoop can be used in several projects like as testing tool, for instance to measure new analogue sensors or in a project, whose goal is the creation of a new fast data source, e.g. based on an FPGA and connected through USB2 and so on. Osqoop, based on Qt 4, a graphical user interface library, is free software under the GNU GPL license and can thus be used and modified freely.

ParaView is a scalable, open-source multi-platform data analysis and visualization application. The application runs on a wide variety of platforms, ranging from a single-processor desktop machine to multi-processor shared-memory supercomputers or clusters of computers. ParaView was developed to analyze extremely large datasets using distributed memory computing resources. It can be run on supercomputers to analyze datasets of terascale as well as on laptops for smaller data. When run in a parallel environment, ParaView can process very large data in a wide variety of data formats (structured and unstructured, time varying and static). ParaView provides a comprehensive suite of visualization algorithms and supports many different file formats for both loading and exporting datasets, for example;

• ParaView files: this is the default file format for ParaView;
• VTK files: this is the XML-based file format used by VTK aka the Visualization ToolKit, an open source, freely available software system for 3D computer graphics, image processing, and visualization;
• pdb files (Protein Data Bank);
• ...and many many other!

This application is extensible, so new algorithms can be easily added. ParaView users can quickly build visualizations to analyze their data using qualitative and quantitative techniques. The data exploration can be done interactively in 3D or programmatically using ParaView's batch processing capabilities. It has a client-server architecture to facilitate remote visualization of datasets, and generates level of detail (LOD) models to maintain interactive framerates for large datasets. Parts of ParaView are under various licenses (ParaView license, VTK license, Los Alamos license and so on), for details click here.

           

QtDMM is a DMM (Digital Multi Meter) readout software (for Linux/UNIX and since version 0.8.11 for Mac OS X) including a configurable transient recorder. The transient recorder features manual start, scheduled start (at a given time) and triggered automatic start when given thresholds are reached. It was written for Metex (and compatible like Voltcraft) multimeter and is known to work with various DMM's, here is a partially list;

• Digitech QM1350;
• ELV M9803R;
• MASTECH M9803R;
• McVoice M-980T;
• Metex M-3660D;
• PeakTech 4010;
• Radioshack 22-805 DMM;
• Voltcraft M-3650D;
• ...and many others!

here a complete list. For more information click here. There is, also, the 2nd version of QtDMM, aka QtDMM2, which will be a GUI for multimeter based on Qt-4.x. The impementation is in an early larval stage. The most important difference between QtDMM and QtDMM2 will be the separation of front- and backend (cdmm) and the ability to handle more than one multimeter at once (even over network).
