Connecting the DUT
Connecting the DUT - Concepts
This section provides information on how to connect your DUT for several common
test scenarios.
N O T E
The pattern generator's Data Out, Aux Data Out, Clock Out and Trigger/Ref Clock
Out ports must be terminated with 50 Ω if they are not connected.
N O T E
The error detector's Clock In connector must be terminated with 50 Ω if they are
not in use.
The following procedure is recommended when setting up a test:
1
If your DUT can handle 0V, press the 0V (Disable) button in the PG Setup -
Data Output or PG Setup - Clock/Trigger Output screen.
The pattern generator's Data Out, Aux Data Out, Clock Out and Trigger/Ref
Clock Out outputs are set to 0V. This is indicated in the PG Setup - Data
Output or PG Setup - Clock/Trigger Output screen.
2
Connect the DUT as necessary.
3
Terminate any non-connected Data Out, Aux Data Out, Clock Out and Trigger/
Ref Clock Out ports (normal and complementary).
4
If the outputs are disabled, press the 0V (Disable) button to enable them.
To avoid damaging your device, set up the devices properly before making
connections.
C A U T I O N
ESD can damage or destroy electronic components. Coaxial cables with both ends
unconnected may store electrostatic charges. Before connecting any coaxial cable
of this sort to a device or instrument, momentarily short the center and outer
conductors of the cable. When making connections, ensure the proper use of a
grounded, resistor-isolated wrist strap.
Connect your device according to the diagrams below:
