Differential Signals AC Input Parameters Tests
Probing for Differential Signals AC Input Parameters Tests
When performing the Differential Signals AC Input Parameters tests, the DDR1 Compliance Test
Application will prompt you to make the proper connections. The connection for the Differential
Signals AC Input Parameters tests may look similar to the following diagram. Refer to the Connection
tab in DDR1 Compliance Test 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 DDR1 Compliance Test
Application. (The channels shown in

Ensure that the RAM reliability test software is running on the computer system where the DDR
Device Under Test (DUT) is attached. This software will perform a test on all unused RAM on the
system by producing a repetitive burst of read-write data signals to the DDR memory.
