Cursor Types
These cursors can be placed on most Channel, Memory, Math or Zoom traces:
l Horizontal (Time) cursors intersect two points on the horizontal axis. The readout shows absolute
values and a delta of the two points.
l Vertical (Amplitude) cursors intersect two points on the vertical axis. The readout shows absolute
values and a delta of the two points.
l The Horizontal + Vertical option places both cursors together.
Two other cursors are offered only in special circumstances:
l Horizontal (Frequency) cursors look the same as Horizontal (Time) cursors except that they are
placed on waveforms that have frequency on the x-axis, such as FFTs.
l Horizontal (Event) cursors are placed only on Trend waveforms.
Apply and Position Cursors
Apply Cursors
To turn on cursors, either:
l From the menu bar, choose Cursors and select the desired cursor type from the drop-down list.
l On the front panel, press the Cursor button to turn on cursors, then continue pressing to cycle
through all the cursor types. Stop when the desired type is displayed.
Note: There must be a waveform on the grid for cursors to execute, although acquisition may be in
process or stopped when you turn them on.
To turn off cursors, choose Cursors > Off from the menu bar, or continue cycling the Cursor button until
you reach "Off" (the cursor lines disappear).
Position Cursors
The easiest way to reposition a cursor is to drag-and-drop the cursor marker to a new position. Indicators
outside the grid show to which trace the cursor belongs when you have multiple traces on one grid.
Alternatively, use the front panel Cursor knob. Push the knob until the correct line is selected, then turn to
move it. The third press of the Cursor knob selects both cursors so they will track together when the knob
is turned.
When there are multiple traces on the same grid, bring the desired trace to the foreground by touching the
trace or its descriptor box. The Cursor knob will only operate on the foreground trace.
