Track Mode
In this mode, one or two pairs of cursors will appear. You can adjust the two pairs of
cursors to measure the X and Y values on two different sources respectively. The
points being measured on cursor A and B are marked by an orange rectangle and
rhombus respectively. When the cursors are moved horizontally, the marks will
position on the waveform automatically. When the waveform is expanded or
compressed horizontally, the marks will track the points being marked at the last
adjustment of the cursors.
Press Cursor  Mode  “Track” to turn on the cursor track function and the
measurement results will be displayed at the upper left corner of the screen in the
following mode.
 A->X : the X value at cursor A. X value takes the trigger position as reference
and “s” or “Hz” (when measuring FFT waveform) as its unit.
 A->Y: the Y value at cursor A. Y value takes the channel GND as reference and
uses the same unit as the current source.
 B->X: the X value at cursor B . X value takes the trigger position as reference
and “s” or “Hz” (when measuring FFT waveform) as its unit.
 B->Y : the Y value at cursor B. Y value takes the channel GND as reference and
uses the same unit as the current 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.
If needed, please refer to the following steps to modify the track cursor
measurement parameters.
