Using cursors to display frequency and amplitude levels
Displaying harmonics
• To identify the harmonics of a peak, move the cursor to the
peak of interest. If the harmonic cursors option has been
turned on (see below), additional cursors are displayed at
frequency or time values that are whole-number multiples of
the frequency or time value indicated by the main cursor.
• To turn on harmonic cursors press
to access the
Display Options Menu then press
