4. Press the CURSO
R button to display the measurement cursors.
5. Position the first timing cursor at the left edge of the zero-crossing point of
the Eye wavefo
rm. (See Figure 56.)
NOTE. If necessary, use the Gain and Sweep controls for better vertical and
horizontal resolution. (See page 89, Gain, Sweep, and Magnification.)
6. Position the second timing cursor at the right edge of the zero-crossing point
of the Eye waveform. (See Figure 56.)
7. Check that the Delta readout is less than the following: (See Figure 56.)
