Cursor Measurements
1. For greater measurement accuracy, the oscilloscope provides cursors that will be used in the next
series of steps.
a. Push the front-panel Cursor button to display the cursor menu.
b. The Type side-bezel button allows you to select either the Amplitude or the Time cursors.
• The amplitude cursors measure voltage along the vertical axis.
• The time cursors measure time along the horizontal axis.
• The active cursor is displayed as a solid line, while the inactive cursor is displayed as a
dotted line.
Push the Type side-bezel button until Amplitude cursors are selected.
c. Notice that the Cursor 1 side-bezel readout is highlighted and the LED next to the multipurpose
control is lit. Turn the multipurpose control to position the upper horizontal cursor on top of the
waveform.
d. Push the Cursor 2 side-bezel button. Turn the multipurpose control to position the lower
horizontal cursor on the bottom of the waveform. Write the signal amplitude from the center right
edge of the display in the Exercise section below.
