Visual Analyser: Virtual Oscilloscope :)

Visual Analyser is a complete professional real time software, transform your PC in a complete set of measurement instruments; no new hardware necessary (you can use the Sound Card of your PC) or you can use a specific external hardware.




Features :

1) Oscilloscope (dual channel, xy, time division, trigger);

2) Spectrum Analyzer with amplitude and phase display (linear, log, lines, bar, octaves band analysis 1/3, 1/6, 1/9, 1/12, 1/24);

3) Wave-form generator with "custom functions", triangular, square, sinus, white noise and pulse generation (NO ALIASING);

4) Frequency meter (in time and frequency domain) and counter; in time domain by means of a real time zero crossing algorithm;

5) Volt meter with DC, true RMS, peak to peak and mean display;

6) Filtering (low pass, hi pass, band pass, band reject, notch, "diode", DC removal);

7) Memo windows (data log) for analysis and storage of time series, spectrum and phase  with "triggering" events; possibility to save in various formats and display them with a viewer;

8) A TRUE software digital analog conversion (for complete signal reconstruction using Nyquist theorem) ;

9) Frequency compensation: one can create/edit a custom frequency response and  add it to the spectrum analyzer spectrum ; added standard weighting curves A,B,C in parallel with custom frequency response;

10) Support for 8/16/24 bit soundcard by means of API calls;

11) Unlimited frequency sampling (depend from the capabilities of your soundcard);

12) Cepstrum analysis;

13) Cross Correlation;

14) Extended THD measurements, with automatic sweep and compensation.

15) ZRLC-meter with Vector scope, automatic sweep in time and frequency for automatic measurement.
