The FFT and 1/3 Octave Spectrum Analysers, used for
determining frequency content of a signal, are included in
the following MSD100 models:
•
MSD100T-SA
•
MSD100AES-SA
The FFT-analyser is used as an accurate measuring tool,
the 1/3-octave analyser shows the energy distribution of
the signal.
4.11.1 FFT Spectrum Analyser
The FFT Analyser uses a complex Fast Fourier
Transformation (FFT) algorithm that outperforms earlier
analogue counterparts in the number of frequency bands
and indication range.
This analyser uses a 1024-band FFT algorithm to display
the signal content between 44Hz and 20kHz, covering the
dynamic range from –70 to +10dBu. These improvements
