 △X: the horizontal difference between cursor A and B.
 1/△X: the reciprocal of the horizontal difference between cursor A and B.
 △Y: the vertical difference between cursor A and B.
Note: The display mode of the measurement results displayed at the upper left
corner of the screen will be different in different cursor display mode, measurement
source and units currently selected. When the vertical unit is set to “Source Unit”:
 In X (or Y) display mode, A->Y, B->Y and △Y (or A->X, B->X, △X and 1/△X) will
not be displayed.
 When the measurement source is MATH (FFT), the units of A->Y and B->Y are
“dBV” and the unit of △Y is “dB”.
 When different horizontal unit is selected, the unit of A->X, B->X, △X and 1/△X
is different (for the details, please refer to the introduction below). When the
horizontal unit is set to “°” or “%”, 1/△X will not be displayed.
When the measurement source is set to LA, the display mode will be set to X
automatically and the measurement results will be displayed in the following form.
 CurA: the X value at cursor A. X value takes the trigger position as reference.
 D15D0: display the logic level values at cursor A (D15-D0 from left to right) in
hexadecimal and binary forms. If the digital channel is currently turned off, it will
be denoted by X in the binary data.
 CurB: the X value at cursor B. X value takes the trigger position as reference.
 D15D0: display the logic level values at cursor B (D15-D0 from left to right) in
hexadecimal and binary forms. If the digital channel is currently turned off, it will
be denoted by X in the binary data.
 △X: the horizontal distance between cursor A and cursor B.

Press DisplayMode to select “X”, “Y” or “X-Y”.
 The X cursors are a pair of vertical solid/dotted lines and are usually used to
measure time parameters.
