OscilloMeter - Spectrum Analyzer 4.14
OscilloMeter - Spectrum Analyzer - 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 on time and on frequency
simultaneously. Smoothing windows (weighing an input signal) - more than 50 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. The following parameters can be measured in real time mode: Peak
Frequency, Peak Amplitude, Total Power, Signal to Noise Ratio (SNR), Signal to Noise plus
Distortion Ratio (SINAD), Spurious-Free Dynamic Range (SFDR), Effective Number Of Bits (ENOB),
Total Harmonic Distortion (THD), Inter-Modulation Distortion (IMD), Direct Current Offset, Peak
Phase Difference. Holding or decaying maximum values of spectra. The Demo version 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.
