Monitoring the S
DI Physical Layer
4. Press the CURSOR button to display the
measurement cursors.
5. Position the first timing cursor at the left
edge of the zero
-crossing point of the
Eye waveform.
NOTE. If necessary, use the Gain and
Sweep control
s for better vertical and
horizontal resolution.
6. Position the second timing cursor at the
right edge of t
he zero-crossing point of
the Eye waveform .
7. Check that the Delta readout is less than
the following:
