Differential Signal AC Output Parameters Tests

Probing for Differential Signals AC Output Parameters Tests

When performing Differential Signals AC Input Parameters tests, the DDR2(+LP) Compliance
Test Application will prompt you to make the proper connections. The connection for Differential
Signals AC Output Parameters tests may look similar to below diagram. Refer to the Connection tab
in DDR2(+LP) Electrical Performance Compliance application for the exact number of probe
connections.

You can use any of the oscilloscope channels as Pin Under Test (PUT) source channel. You can
identify the channels used for each signal in the Configuration tab of the DDR2(+LP) Compliance
Test Application. (The channels shown in

on page 27.
Ensure that the RAM reliability test software is running on the computer system where the
DDR2/LPDDR2 Device Under Test (DUT) is attached. This software will perform test on all the
unused RAM on the system by producing repetitive burst of read-write data signals to the
DDR2/LPDDR2 memory.
Connect the differential solder-in probe head to the PUTs on the DDR2/LPDDR2 devices.
Connect the oscilloscope probes to any channels of the oscilloscope.
In the DDR2/LPDDR2 Test application, click the Set Up tab.
