Time cursors appear as vertical lines on the display and measure the
horizontal parameters. You can move the cursor by turning the
Adjust front panel knob. Before using cursors, you should make sure
that you have set the signal source as the channel for measuring.
2. Track - displays two cross-cursors. The cross-cursors set the position
on the waveform automatically. You can adjust the cursor position
on the waveform by turning the
Adjust front panel knob. The values
are displayed on the top of the grid display.
3. Auto - Automatically places markers of what is being measured on
the waveform. These markers clarify parameter measurements by
displaying cursors and a visual representation of what is being
measured. When in Auto cursor mode, as you select measurement
parameters the markers will be displayed for the measurements.


Time cursors are vertical lines that you move horizontally to
measure the difference in time or frequency values between the
cursors.

Voltage cursors appear as horizontal lines on the display and
measure the vertical parameters.

The measurement values listed on the top of the grid display are as
follows:
A→T - the horizontal position of Cursor A (Time cursor centered
around the midpoint of the screen)
A→V - the vertical position of Cursor A (Voltage cursor centered
around the channel ground level)
B→T - the horizontal position of Cursor B (Time cursor centered
around the midpoint of the screen)
B→V - the vertical position of Cursor B (Voltage cursor centered
around the channel ground level)
ΔT - Horizontal space between Cursor A and Cursor B (Time value
between the two cursors)
1/ΔT - the reciprocal of the horizontal space between Cursor A and
Cursor B
