Connecting the Clock Source and the Device Under Test
As shown in Figure 7-3 on page 222 , there are numerous ways to provide a common frequency reference to
the system components (ESG, N5102A module, and the device under test). Figure 7-8 shows an example
setup where the signal generator supplies the common frequency reference and the N5102A module is
providing the clock to the device.
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.
