Measuring with Cursors
Overview
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.
Cursor Types
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.
Cursor Types include Absolute, Delta, Abs+Delta, and Slope. The following
topic explains them and other cursor information in a bit more detail.
Cursors Setup
Quickly Displaying Cursors
Cursors can always be quickly turned on and off from the touch screen or
the front panel control, respectively as follows:

Touch Cursors on the menu bar and make cursor control selections
as desired. Off, Horizontal Abs, Horizontal Rel, Vertical Abs, and
Vertical Rel options are available on the menu.

Press the C URSOR T YPE button on the front panel repeatedly for all
the available cursor types on your instrument. Turn the C
URSORS
knobs to adjust the position of the cursor.
