Using Vertical Cursors on a Waveform
To use the cursors for a time measurement, do the
following:
From Scope mode, display the
Cursor Key functions.
Press to highlight
. Observe
that two vertical cursors are
displayed. Markers (-) identify the
point where the cursors cross the
waveform.
If necessary, choose the trace A
or B.
Highlight the left cursor.
Move the left cursor to the desired
position on the waveform.
Highlight the right cursor.
Move the right cursor to the
desired position on the waveform.
Figure 2-19. Time Measurement with Cursors
The readout shows the time difference ‘t’ between the
cursors and the voltage difference between the two
markers (See Figure 2-19).
The signal frequency is displayed behind 1/t if exactly 1
signal period is between the cursors.
