Visual Analyser 4.0: Great Oscilloscope and Spectrum Analyser (Windows)

One Great Freeware Application

Software Located Here: Visual Analyser


  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.
