You can change the type of cursor to display different types of information on a plot. The types of cursors vary based on the selected plot type.

F2 Cursor Type until the appropriate cursor
Option Description Delta Time The amplitude and time of the current location are shown just below the plot. When you press the Mark key, the current location is marked. As you move the cursor, the time difference (Delta-T) between the marked point and the new cursor position displays in the upper right corner of the plot. The screen displays a frequency (Delta-F), which is calculated as the reciprocal of the time difference. This is useful for waveforms. Difference Family The difference families of the data are calculated and the first family is used to draw the difference cursors. This is similar to the “Sideband” cursors, but the “Next Peak” key changes to a “Next Family” key. This lets you jump through the calculated difference families, and increases the number of sideband cursors. Harmonic The primary cursor is red and all harmonics related to the primary frequency are displayed with black square boxes. Harmonic Family The harmonic families of the data are calculated and the first family is used to draw the harmonic cursors. This is similar to the Moving harmonic option, except that you can jump to the next family of harmonics rather than the next peak. Moving Harmonic Similar to the Harmonic cursor, but the fundamental frequency is not stationary. As you move the cursor, the harmonic markers move to reflect the harmonic frequencies of the current cursor location. Normal An individual cursor appears on the plot. The frequency and amplitude update as you move the cursor. Sideband Displays the Delta-F and values between a reference and active cursor (Delta-A).
