OscilloMeter - Spectrum Analyzer 4.14

Oscillometer is intended for real-time investigation of data accepted from any ADC you will want.

Oscillometer consists of an oscilloscope and spectrum analyzer. Maximum numbers of channels, sampling frequency, bit rate of data, frequencies range, precision are limited only by type of used ADC.

The obtained data and images can be saved to files or clipboard. Oscilloscope modes (for dual-channel ADC): original signals, sum, difference, dependence of one channel on another, amplitude distribution of input signals.

The synchronization is independent in each of panel. Spectrum analyzer works on algorithm of Fast Fourier transform (FFT). The size of the FFT block is up to 2^20 (1 M) samples of input signal.

The processing of overlapped in time series of samples of an input signal for combination of high resolution of the analysis on time and on frequency simultaneously. Smoothing windows (weighing an input signal) - more than 40 types.

Averaging of results of some FFT: equally weighted - scalar or vector; exponentially weighted - scalar. Number of averaging transforms is from 2 up to 20 or infinite. Synchronization of the spectrum analyzer is independent from oscilloscope. Holding or decaying maximum values of spectra.

The Demo version works with ADC of a sound card and is a fully functional copy of OscilloMeter with the exception that input time is limited to 15 seconds after each "Start" button click. The registration removes demonstration limitation.
