Calculate THD option will calculate the Total Harmonic Distortion of auto-power
spectrum signals between the two vertical cursors. The CoCo looks for a peak near
the left cursor to use as the primary frequency.

When displaying Frequency Response signals, there is a Calculate Damping
feature. This will search between two vertical cursors to find the resonant
frequency and damping factor of a structural response signal.
