Cursors
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 Sub-types
include
Absolute
,
Delta
,
Abs+Delta
, and
Slope
.
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 mode.
Cursors Setup
Quickly Displaying Cursors
Cursors can always be quickly turned on and off from either the
touchscreen display or the Front Panel:
On the display, touch
Cursors
on the menu bar and make a
selection.
Off
,
Horizontal Abs
,
Horizontal Rel
,
Vertical Abs
, and
Vertical Rel
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
