Reference (only in the route / machine template mode)
Here you can compare the current spectrum with a reference
spectrum or a historical spectrum. The spectra are displayed in a
'waterfall' diagram (see also p. 4-13).
Zoom / Scaling See 'Time waveform', page 4-4.
Cursor
• Press the MENU key and click on 'Cursor' (see below)
None /Main / Delta: See 'Time waveform', page 4-5.
Harmonics: Show/hide harmonic cursor
The harmonic cursor is used to assign harmonics in the spectrum.
The spacing of the individual cursors to one another corresponds
to the basic frequency at the main cursor. To adjust this, the main
or the delta cursor (highest displayed order) can be moved.
• Adjust the required number of the cursors.
Subharmonics: Show/hide subharmonic cursor
The subharmonic cursor can be used to detect subharmonics
in the spectrum. The spacing of the individual cursors to one
another corresponds to a integer fraction (1/n) of the main cursor.
• Adjust the required number of the cursors.
If the subharmonic cursor is activated, the delta cursor is not active.
Note
Sidebands: Show/hide sideband cursor
The sideband cursor can be used to identify modulations of a
carrier frequency. The distance of the sidebands can be set by
moving the outer cursor (press 'Enter' to change over, P. 4-5).
Change the carrier frequency by moving the main cursor.
• Adjust the required number of the cursors.
