XY Mode
XY mode is only available when the horizontal time base mode is "XY". In this mode,
two pairs of cursors will appear. You can adjust the cursor positions and the
instrument will automatically calculate the chord length and curvature of the ellipses
corresponding to the crossing points of the two pairs of cursor lines.
Press Cursor  Mode  "XY" to enable the XY mode cursor measurement function.
The measurement results are displayed at the upper left corner of the screen in the
following mode.
 AX: the X value at cursor AX.
 AY: the Y value at cursor AY.
 BX: the X value at cursor BX.
 BY: the Y value at cursor BY.
 BX-AX: the horizontal difference between cursors BX and
AX.
 BY-AY: the vertical difference between cursors BY and AY.
 dX*dY: the product of the horizontal difference between
cursors BX and AX times the vertical difference between
cursors BY and AY.
 dX/dY: the quotient of the horizontal difference between
cursors BX and AX divided by the vertical difference
between cursors BY and AY.
 absAA: the chord length of the crossing point of cursors
AX and AY relative to the center point. The center point is
defined as the crossing point of the horizontal position
(X-axis) and the vertical position (Y-axis) of two channel labels on the screen as
shown in Figure 6-8.
 absAB: the chord length of the crossing point of cursors AX and BY relative to
the center point.
 absBA: the chord length of the crossing point of cursors BX and AY relative to
the center point.
 absBB: the chord length of the crossing point of cursors BX and BY relative to
the center point.
 argAA: the angle between X-axis and absAA. The range is from -180° to +180°.
 argAB: the angle between X-axis and absAB. The range is from -180° to +180°.
 argBA: the angle between X-axis and absBA. The range is from -180° to +180°.
 argBB: the angle between X-axis and absBB. The range is from -180° to +180°.
