 A->X: the X value at cursor A. X value takes the trigger position as reference.
 B->X: the X value at cursor B. X value takes the trigger position as reference.
 A->Y: the Y value at cursor A. Y value takes the channel GND as reference.
 B->Y: the Y value at cursor B. Y value takes the channel GND as reference.
 △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.
If needed, please refer to the following steps to modify the parameters of manual
cursor measurement.
1. Select Display Mode
Press Display Mode 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. The
Y cursors are a pair of horizontal solid/dotted lines and are usually used to
measure voltage parameters. The X-Y cursors are a pair of vertical solid/dotted
lines and a pair of horizontal solid/dotted lines and are usually used to measure
time and voltage parameters at the same time.
2. Select Measurement Source
Press Source to select the waveform of the analog channels (CH1 or CH2) or
math operation results (MATH) for measurement. If “None” is selected, no
cursor will be displayed.
3. Select Screen Region
 When Zoom is enabled (pressing the HORIZONTAL SCALE can enables
Zoom), the screen is divided into two regions, Main and Zoom. When “Main”
is selected, the cursors are displayed in the main region and measure the
signal displayed in the main region. The measurement results are displayed
in the zoom region. When “Zoom” is selected, the cursors are displayed in
