Bitscope - PC oscilloscopes and analyzers

Tuesday, 13 July 2010 20:23

BS100 is a high performance isolated USB Mixed Signal Oscilloscope designed for use with a PC or notebook: 100 MHz Analog Input Bandwidth, Dual Converters with 4 inputs (BNC & POD), 8 logic/timing channels and Smart POD, 40MS/s Logic Analyzer, 25nS capture, DSP Waveform Generator (option), Real-Time Spectrum Analyzer, Mixed Signal Data Recorder, Electrically Isolated USB, User Programmable A versatile data acquisition system packs a digital oscilloscope, spectrum analyser, logic analyser, data recorder and waveform generator into one affordable package. BitScopes are USB or Ethernet connected PC Based Mixed Signal Oscilloscopes. This means they capture and display one, two or four analog signals and eight logic or timing signals, simultaneously. Any BitScope can be used as a:

Digital Storage Oscilloscope;
Logic State Analyzer;
Spectrum Analyzer;
Data Recorder.

Some models include an Arbitrary Waveform Generator (AWG) and all of them have a Smart POD expansion connector on the front for logic probes and external signal processing modules. If you design, test or repair embedded systems, work with microcontrollers, robotics, sensors and servos, or modern automotive, avionic or other control systems you'll inevitably find you need to see analog and digital or logic signals simultaneously and time synchronized. Programming Library and Custom Applications for BitScope, a.k.a. BitLib, is a powerful but easy to use library for creating custom BitScope applications. BitLib comes with some applications (including source) to get started using it straight away:

Digital Storage Oscilloscope: The BitLib Scope application is a program built with BitLib that implements a single channel oscilloscope. It demonstrates many of the analog capture capabilities of BitScope. BitScopes are Mixed Signal Oscilloscopes;
Multichannel Digital Voltmeter: The BitLib Meter application is a program built with BitLib that implements a useful multi-channel voltmeter: a practical real-time 4 channel digital voltmeter. It demonstrates how to use all analog inputs at once (2 x BNC + 2 x POD) as well as the calibration features of the library;
Arbitrary Waveform Generator: The BitLib Generator is a BitLib application similar to BitLib Scope but which demonstrates the waveform generation capabilities of BS3xx BitScope models. an arbitrary waveform generator to synthesize functions or replay real-world waveforms recorded with DSO's built-in data recorder;
Data Acquisition Spreadsheet: BitLib Sheet is a BitLib example that that demonstrates how BitScope can be integrated into a third-party numerical analysis tool as a live data source;
Transient Data Recorder: The BitLib Recorder is a BitLib application similar to BitLib Scope but which demonstrates the streaming capture and recording capabilities of newer BitScope models. A data recorder which creates CSV waveform data files.

Software Applications for BitScope Mixed Signal Oscilloscopes are:

BitScope-DSO: it is much more than just oscilloscope software for your PC. It provides a full range of test instruments in one easy to use software package. Integrated functions include: Digital Storage Oscilloscope, Mixed Signal Oscilloscope, Spectrum Analyzer, Logic Analyzer, Data Recorder, Networking. DSO takes full advantage of BitScope's powerful mixed mode waveform and logic data capture capability. And in BitScope models that support it, DSO adds arbitrary waveform generation (AWG) networked access for remote measurement and data acquisition as well as offline captured waveform replay and multiscope control, all accessed from the one PC software application. It's fast and intuitive;
BitScope-meter: it is an oscilloscope, AC/DC voltmeter and frequency meter in one easy to use package. t's like a waveform generator in reverse. Plug-in any waveform and WaveMeter will lock on and display it while simultaneously reporting waveform parameters in realtime. Features and benefits include: Real-time waveform display, Dynamic parameter reporting, Automatic frequency/period meter, Peak, RMS & Min/Max voltmeters, DC mean and offset voltmeters, Sophisticated auto-locking trigger, Fast point & click operation. WaveMeter is an ideal tool to quickly view and measure AC/DC signals and voltages. There are no complicated parameters, just connect the signal and view the results!

DSO-101, DVM-101, WGM-101/201 & CGR-101 - An electronic Lab in your pocket

Sunday, 25 January 2009 23:28

DSO101 (Digital Storage Oscilloscope), WGM101 and WGM201 (Waveform Generator) and CGR101 (Circuit Gear) are software for instruments Syscomp Electronic

. The DSO-101 is an USB-powered digital storage oscilloscope with dual 20MS/s inputs and a 2MHz bandwidth; it packs some powerful features including a hardware preamp, adjustable digital triggering, and 32kB memory depth on each of the two 8 bit input channels. The DSO-101 is powered by an open-source graphical user interface for GNU/Linux. The fully functional, easy to use software supports multiple triggering modes, waveform scrolling, saving waveforms to a file, and cursor measurements. Source code is included. The user can add and modify the graphic user interface as desired. WGM-101 USB Waveform Generator

The WGM-101 is an USB-powered waveform generator. This device generates all standard test waveforms (Sine, Square, Triangle, Sawtooth) as well as arbitrary waveforms created by the user. Precise digital frequency control allows adjustment of the output frequency from 0.1Hz to 100kHz with a resolution of 0.1Hz. The open source graphical user interface (WGM101) allows the user to download custom waveforms into the device for non-volatile storage, sweep the frequency over a particular frequency range with a point-and-click interface, and directly control the output amplitude and offset. Circuit Gear is an oscilloscope, waveform generator, and digital I/O port integrated into one small, low cost unit. Here is some features;

20MS/s dual channel, 10-bit oscilloscope;
2 MHz DDS arbitrary waveform generator;
Eight channel digital I/O;
USB powered, no AC adaptor required;
Open source software for GNU/Linux (and others SOs).

The current releases of software provide basic features for the instruments, but there are many that could be added. For example, the oscilloscope would benefit from 'waveform math' commands. The waveform generator could be configured as an audio sweep generator and so on.

Fityk - Data analysis software

Saturday, 13 December 2008 14:30

Fityk is a program for nonlinear fitting of analytical functions (especially peak-shaped) and data analysis software (usually experimental data). There are also people using it to remove the baseline from data, or to display data only. It supports data visualization, separation of overlapping peaks, and least squares fitting using standard Levenberg-Marquardt

algorithm, a genetic algorithm, or Nelder-Mead

simplex method. It knows common bell-shaped functions (Gaussian, Lorentzian, Pearson 7, Voigt, Pseudo-Voigt) and polynomials, but more sophisticated formulae can be added if needed. It also enables background substracting, data calibration and task automation with a simple script language. It is being developed to analyze powder diffraction patterns, but can be used to fit analytical functions to any kind of data, e.g. it's reportedly used in crystallography, chromatography, photoluminescence and photoelectron spectroscopy, infrared and Raman spectroscopy

, and more. Fityk offers intuitive graphical interface (and also command line interface), variouse optimization methods (standard Marquardt least-square algorithm, Genetic Algorithms

, Nelder-Mead simplex), equality constraints, modelling error of x coordinate of points (eg. zero-shift of instrument), handling series of datasets, automation of common tasks with scripts, and more. For more information click here here
