Cursors
Cursors are markers (lines or cross-hairs) that identify specific voltage and time values on the waveform.
Use cursors to make fast, accurate measurements of specific points in the waveform. There are three,
standard cursor types available.
Vertical (amplitude) cursor readouts appear the descriptor box for the trace; Horizontal (time) cursor
readouts appear below the Timbebase descriptor box.
Horizontal and vertical cursors.
Cursor Types
Standard Cursors
These cursors can be placed on most any Channel, Memory, Math or Zoom trace.
Horizontal (Time) cursors place vertical lines through a desired point along the horizontal axis.
Vertical (Amplitude) cursors place horizontal lines through a point on the vertical axis.
An option exists to place Horizontal + Vertical cursors together.
Special Cursors
Some 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.
In addition, some optional software packages provide cursors and help markers that are specific to the
application.
