Comments
The Bands FFT is calculated from a fixed sample size time waveform. Therefore
the number of spectrum lines is fixed and dependent on the decimation and
filtering applied.
Decimation
None Alternate Path
1800 1000
Synchronous sampling (alternate path) is also a form of decimation, so it
processes a1000 line FFT (over the specified number of orders).
