Phase spectrum
If a time signal is measured together with a tachometer
pulse, a phase spectrum can be displayed.
To view a phase spectrum, go to the Spectrum window
and press MENU > ‘Phase spectrum’ (1).
The blue cursor (3) is displayed by default. It can be
removed with F2 (‘Cursor’) > F1 (‘Cursor A’). For the
marker position in the spectra, frequency, amplitude
and phase angle are shown (4).
Move the blue marker with the LEFT/RIGHT arrow keys.
In the Phase spectrum window, you can select MENU
> ‘Show phase noice’ (2) to see the phase angle for
each line included in the spectra.
All other settings and graphical functions are the same
as for spectrum, see ‘Spectrum functions’ earlier in this
part of the manual.
