7. Use the left and

right a rrow keys to position the right cursor.

NOTE. Even when the key labels are not displayed a t the bottom of the screen,

you still can use the arrow keys. This allows full control of both cursors while

having a full screen view.

8. Use the cursors to measure the time and voltage differences.

This screen shows the time difference between the two cursors and the voltage

difference between the two markers. (See Figure 29.)

Curs

ors on a Waveform

The steps to measure either rise time or fall time are similar. To measure rise

tim

e using cursors, do the following:

1. Press the Cursors button

2. Select the

cursor. The cursor type options are:

׀ : Single vertical cursor

׀׀ : Two vertical cursors

: Two horizontal cursors

: Rise time cursor

: Fall time cursor
