Constant Band Tracking feature consists in Order analysis calculation based on energy summation from FFT data. Summation band (in Hz) defined by user will be fixed over time, through run up or down condition of measurement. Provided tach signal is connected to FFT, energy summation around multiple (integer or not) of rotating frequency will be calculated in real-time. | Constant Band Tracking (CBT) feature consists in Order analysis calculation based on energy summation from FFT data.

FFT Spectrum giving discrete frequency lines, energy summation will be bases on summation of spectral lines values. Minimum number of lines to be taken into account is related to windowing function used for time block filtering. Up to 8 different orders may be extracted per channels. Order selection may be different from one channel to another. | FFT Spectrum giving discrete frequency lines, energy summation will be bases on summation of spectral lines values.
