XY Cursor Measurement
This mode is onle available in the XY horizontal time base mode. In this mode, two
pairs of cursors are displayed. You can adjust the cursor positions and the instrument
will calculate the chord length and ellipse curvature corresponding to the crossing
points of the two pairs of cursor lines automatically.
Press Cursor  Mode  “XY” to turn on the XY mode cursor measurement
function. The measurement results will be displayed at the upper-left corner of the
screen, as shown in the figure below.
 AX: the X value of cursor XA.
 AY: the Y value of cursor YA.
 BX: the X value of cursor XB.
 BY: the Y value of cursor YB.
 BX-AX: the horizontal difference between cursor XB and
cursor XA.
 BY-AY: the vertical difference between cursor YB and
cursor YA.
 dX*dY: the product of the horizontal difference between
cursor XB and cursor XA times the vertical difference
between cursor YB and cursor YA.
 dX/dY: the product of the horizontal difference between
cursor XB and cursor XA divided by the vertical difference
between cursor YB and cursor YA.
 absAA: the chord length of the crossing point of cursor XA and cursor YA relative
to the center point. The center point is defined as the crossing point of the the
horizontal position (namely the V axis) and vertical position (namely the Y axis)
of the two channel labels on the screen.
 absAB: the chord length of the crossing point of cursor XA and cursor YB relative
to the center point. The center point is defined as the crossing point of the the
horizontal position (namely the V axis) and vertical position (namely the Y axis)
of the two channel labels on the screen.
 absBA: the chord length of the crossing point of cursor XB and cursor YA relative
to the center point. The center point is defined as the crossing point of the the
horizontal position (namely the V axis) and vertical position (namely the Y axis)
