Order full spectrum
Set Full Spectrum to yes. Remember to set correct angles of both sensors. It influences the calculation. The
FFT is applied to complex signal, first channel is real part and second channel is imaginary part.
Note: Cursor is displayed on both sides. Different colors are used. Both cursor values are displayed.
Attention!
The correct setting of channel A and B is critical for correct result. If this setting is wrong then the
negative and positive side are interchanged. See Full spectrum for details.
Phase Shift
The measurement of phase shift (between two channel A and B), amplitude ratio and coherence on speed
frequency (with tacho) or manually entered frequency.
The result contains:
- phase shift value in degrees,
- amplitude ratio ( ampl B/ ampl A),
- coherence
If the phase shift is reliable, then the coherence must be bigger then 0.8.
DC
The direct DC signal can be measured by this function.
