N5102A Digital Signal Interface Module
is an example of a phase and skew adjustment and shows the
original clock and its phase position relative to the data after each adjustment.
Notice that the skew adjustment adds to the phase setting.

Clock Phase and Skew Adjustments
Connecting the Clock Source and the Device Under Test
As shown in
, there are numerous ways to provide a
common frequency reference to the system components (PSG, N5102A
module, and the device under test).
shows an example setup
where the signal generator supplies the common frequency reference and the
N5102A module provides the clock to the device.
See the
N5102A Digital Signal Interface Module Installation Guide
for
detailed information on device interface connections.
CAUTION
The Device Interface connector on the interface module communicates using
high speed digital data. Use ESD precautions to eliminate potential damage
when making connections.
NOTE
You must disconnect the digital bus cable and the digital module while
downloading firmware to the signal generator.
