Visual Analyser is a complete professional real time software, transform your PC in a full 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 for example Plug.n.DAQ Lite or RogaDAQ2.

VA is a real time program which simulates a set of electronic instruments, such as:

  • Oscilloscope (dual channel, xy, time division, trigger)

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

  • Wave-form generator with “custom functions”, triangular, square, sinusoidal (all with NO ALIASING and smooth transition), white / pink noise, pulse generation, DC generation [New!]

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

  • Volt meter with DC  [New!], True RMS, peak to peak and mean display plus resolution calculation

  • Filtering (low pass, hi pass, band pass, band reject, notch, “diode”, DC removal)

  • Memo windows (data log) for analysis and storage of time series, spectrum and phase with “triggering” events; THD and Impedance data logging with spline interpolation; possibility to save the graphics in various format (.tee, .txt, .wmf)

  • Screenshot of Spectrum and Scope window

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

  • Frequency compensation: possibility to create / edit a custom frequency response and add it to the spectrum analyzer computed spectrum; added standard weighting curves A, B, C [New!] in parallel with custom frequency response

  • Support for 8/16/24 bit soundcard by means of API calls

  • Internal 80 bit IEEE floating point variables for minimum rounding error

  • Cepstrum analysis , cross correlation

  • Extended THD measurements, with automatic sweep, compensation, data log

  • ZRLC meter with vector scope, automatic sweep in time and frequency for automatic measurement

  • Calibration mechanism (you can calibrate the VA scales directly in VOLT or dB or percent full scale)

  • Set of values ​​computed in real time (peak to peak, peak, crest factor, form factor, true rms, mean, frequency with zero-crossing algorithm)

  • Wave file recording and playback

  • Custom FIR filters
