Programmable scientific and technical graphics optimized for automation of test and measurement systems, data acquisition and post-process. Especially suitable for scientists who would like to make high-performance, precise measurements in the experimental research. Features include powerful visual tools (graphic editor, plot digitizer, base line subtractor), wide set of numeric and symbolic calculations (integration, differentiation, smoothing, etc), linear and nonlinear NLSF (Levenberg-Marquardt) regression analysis, configurable user interface and more. You can visualize, edit and analyze data produced by any instruments with RS-232 interface or another numerical data sources. Embedded ActiveX-compatible scripting environment allows you easily add new custom operations and integrate this software with popular desktop applications.

Sonic beacon is a PC-based test and measurement system for the testing of loudspeakers and other electro-acoustic products using using a low cost microphone, preamp and a commercially available Windows multimedia sound card. Sonic beacon will perform impedance, frequency and phase response, harmonic and inter-modulation distortion, polarity, sensitivity and SPL as well as other FFT and real time analysis tests. Sixteen bit sampling rates up to 192 kHz and FFT lengths up to 128K points are supported. Sonic beacon contains six virtual instruments that can be cascaded in order to form a process. An input signal emanating from a WAVE audio file, the Signal generator or a sound card may be passed serially from one module to another. Each module performs a process on this signal and alters its time or frequency domain representation. If the modules are coherently cascaded a sensible analysis can be done on the input signal. |
