Measuring with Cursors
Cursors are important tools that aid you in measuring signal values. Cursors
are markers - lines, cross-hairs, or arrows - that you can move around the
grid or the waveform itself. Use cursors to make fast, accurate
measurements and eliminate guesswork. There are two basic types:

Horiz(ontal) (generally Time or Frequency) cursors are markers that
you move horizontally along the waveform. Place them at a desired
location along the time axis to read the signal's amplitude at the
selected time.

Vert(ical) (Voltage) cursors are lines that you move vertically on the
grid to measure the amplitude of a signal.
Each cursor locates a point on the waveform. The cursor values can be read
in the descriptor label for the trace. Use the Position data entry controls at
the right side of the dialog to place the cursors precisely. The Readout
icons depict what is being measured for each measurement mode.
Quickly Displaying Cursors
Quickly turn on/off cursors from either the touchscreen or the Front Panel:

On the display, touch Cursors on the menu bar and make a selection.
Off, Horizontal Abs, Horizontal Rel, Vertical Abs, Vertical Rel, and
BothRel options are available on the menu.

On the Front Panel, press the Cursor Type button repeatedly to
scroll through all the cursor types available on your instrument. With
the desired cursor type selected, turn the Cursors knobs to adjust
the position of the cursor.
PLEASE NOTE THE FOLLOWING:

The bottom cursor knob adjusts relative cursors. It does not work with
absolute cursor types.

Once set, cursor positions are preserved for subsequent displays. Use the
touch screen or front panel controls to change cursor positions or
measurement modes.
