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 five, 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.
The easiest way to apply cursors is to repeatedly press the front panel
Cursor button
until the desired cursor type is
displayed. Position the cursor lines by touching and dragging them to the desired locations. Use the
Position
data entry
controls at the right side of the Standard Cursors dialog to place the cursor precisely.
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
Both
Horizontal (Time) and Vertical (Amplitude) types at once.
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.
