modes available are "Manual", "Track", and "Auto". When "OFF" is selected, the
cursor measurement function is turned off. When the "Time Base Mode" is "X-Y",
only X-Y cursor mode is available.
Manual Mode
In this mode, you can adjust the cursors manually to measure the X value (or Y
value), X increment (or Y increment) between cursors and the reciprocal of X
increment on the waveform of the selected source (CH1, CH2 or MATH).
Press Cursor

Mode

"Manual" to turn the manual cursor measurement
function on. The measurement results are displayed at the upper left corner of the
screen. You can also press Cursor or Mode continuously to switch to "Manual".
When the measurement parameters are modified, the measurement results will
change accordingly.
When the measurement source is CH1, CH2 or MATH, the measurement results are
as shown in the figure below.

A->X: the X value at cursor A. X value takes the trigger position as reference. Its
unit is "s" or "Hz" (when measuring FFT waveform).

B->X: the X value at cursor B. X value takes the trigger position as reference. Its
unit is "s" or "Hz" (when measuring FFT waveform).

A->Y: the Y value at cursor A. Y value takes the channel GND as reference. Its
unit is the same as that of the current signal source.

B->Y: the Y value at cursor B. Y value takes the channel GND as reference. Its
unit is the same as that of the current signal source.

△
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.
