DDR1 Compliance Testing Methods of Implementation
Connect BNC (male) to SMA (male) adaptor to the deskew fixture on the connector closest to the
yellow pincher.
Ω
Connect the 50 SMA terminator to the connector farthest from yellow pincher.
Connect the BNC side of the deskew fixture to the Aux Out BNC of the Infiniium oscilloscope.
Connect the probe to an oscilloscope channel.
To minimize the wear and tear on the probe head, it should be placed on a support to relieve the
strain on the probe head cables.
Push down the back side of the yellow pincher. Insert the probe head resistor lead underneath
the center of the yellow pincher and over the center conductor of the deskew fixture. The
negative probe head resistor lead or ground lead must be underneath the yellow pincher and
over one of the outside copper conductors (ground) of the deskew fixture. Make sure that the
probe head is approximately perpendicular to the deskew fixture.
Release the yellow pincher.
