Abstract

The research consists in the development of a tool named Visual Analyser. It is a complete professional real time software, that transforms the PC in a complete set of instruments; no new hardware is necessary (one can use the Sound Card of the PC).
Visual Analyser simulates a set of electronic instruments, such as:
- Oscilloscope (dual channel, xy, time division, trigger);
- Spectrum analyser with amplitude and phase display (linear, log, lines, bar, octaves band analysis 1/3, 1/6, 1/9);
- Wave-form generator with "custom functions", triangular, square, sinus, white noise and pulse generation (no aliasing);
- Frequency meter (in time and frequency domain) and counter;
- Volt meter with rms and peak to peak display;
- Filtering (low pass, hi pass, band pass, band reject, notch, "diode", DC removal);
- Memo windows for analysis and file saving of time and spectrum displays;
- A true software digital analog conversion (for complete signal reconstruction).

The magazine Nuovaelettronica in number 232 (september / october 2007) published the article Oscilloscopio e Analizzatore di Spettro per PC and in number 233 (november / december 2007) published the article Analizzatore di Spettro su PC in which the software Visual Analyser is integrated with a proprietary external hardware in order to realize a complete set of electronic instrumentation.
A special thank to the editorial staff of the magazine for the permission to publish the article in this web site.
