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.

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 cor-

responds to a integer fraction (1/n) of the main cursor.

• Adjusttherequirednumberofthecursor.

If the subharmonic cursor is activated, the delta cursor is not active.

sideBands:Show/hidesidebandcursor

The sideband cursor can be used to identify modulations of a car-

rier 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.
