Overview
This is a sound card based dual channel Spectrum Analyzer, providing seven types of views:
- Real time Amplitude Spectrum
- eal time Phase Spectrum
- Real time Auto Correlation Function
- Real time Cross Correlation Function
- Real time Coherence Function
- Real time Gain and Phase (Bode Plot)
- Real time Impulse Response
with adjustable FFT size ranging from 128 to 4194304, adjustable window overlap percentage (0%, 25%, 50%, 75%), and 55 selectable window functions such as Rectangle, Triangle, Hanning, Hamming, Blackman, Kaiser. It supports display in logarithmic scale (dBr, dBV, dBu, dBFS, dBSPL), octave analysis (1/1, 1/3, 1/6, 1/12, 1/24), frequency compensation, frequency weighting (Flat, A weighting, B weighting, C weighting, ITU-R 468 weighting), DC removal, peak hold, averaging, and parameter measurement (THD, THD+N, SINAD, SNR, Noise Level, IMD-SMPTE/DIN, IMD-CCIF1, IMD-CCIF2, Crosstalk, Bandwidth), etc.
The Spectrum Analyzer shares the same Trigger Parameters, Sampling Parameters and Miscellaneous Parameters with the Oscilloscope. Please refer to the relevant sections in the Oscilloscope for details.
