Oscillometer is intended for real-time investigation of data accepted from sound card or other ADC you will want. Oscillometer consists of an oscilloscope and FFT 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. Spectral analyzer works on algorithm of Fast Fourier transform (FFT). Spectrum analysis frequency resolution is up to 524288 bins. The processing of overlapped in time series of samples of an input signal for combination of high resolution of the analysis...
