Harmonic – Used for one channel trace. Results in several cursors positioned to the right of
the primary cursor and at intervals that are at twice the x-axis value of the primary cursor.
For example: When the primary cursor is at 100 Hz, the first harmonic cursor will be at 200
Hz, the second at 400 Hz, the third at 600 Hz, etc. Moving the primary cursor to 400 Hz
would result in the first harmonic cursor residing at 800 Hz, the second at 1200 Hz, etc.
With the use of Annotation, values will be shown for all cursors.
The Main Cursor & 5 Harmonic Cursors
Peak – Used for one channel trace. This selection will set up to 20 cursors (according to the
cursor setting in Display Preferences) and automatically position them to the highest peaks
on the trace. Note that the Annotation frame will only provide X and Y values for up to 6
cursors.
FreeForm – Used for one channel trace. This selection will set up to 20 cursors (according
to the cursor setting in Display Preferences). The user can move the freeform cursors to any
desired points on trace. Note that the Annotation frame will only provide X and Y values for
up to 6 cursors.
