Chapter 4 Measurement Definition
Number of Spectrum Lines Fixed at 1800, 1000, or 600. 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.
Synchronous sampling (alternate path) is also a form of decimation, so it
processes a1000 line FFT (over the specified number of orders).
