Probing For Data Strobe Timing Tests; Test Procedure - Keysight U7233A Testing Notes

7 Data Strobe Timing (DST) Tests

Probing for Data Strobe Timing Tests

When performing the Data Strobe Timing tests, the DDR1 Compliance Test Application will prompt
you to make the proper connections. The connection for Data Strobe Timing 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. Typically, you need minimum three probe connections to run the
tests.

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.
