Connecting to your Target System
To connect the probe to the DDR2 bus, select an available DDR2 slot. Remove the
DDR2 DIMM module, if present. Install the DDR2 DIMM module into the 240 pin
connector on the top of the FS2334 probe.

Install the DDR2 probe/DIMM into the target system.
Connect the supplemental power supply to the FS2334.
Connect the FS2334 Headers directly to the logic analyzer pods per the configuration
file requirements if not done prior to installing the probe. Refer to the General Purpose
Probe.

Signal Isolation on the Probe
All signals sent to the logic analyzer from the FS2334 DDR2 probe are isolated from the
DDR2 DIMM bus by a parallel RC network of 20K ohms and .3 pF. These resistors are
placed in a manner to minimize stubs seen by the DIMM bus and to match lengths to the
DIMM module so that Data bits and their Strobe/Mask bits are matched to within 20 ps.

Buffered signals on the probe
The DDR2 DIMM bus Control signals are buffered on the probe before they are
connected to the DIMM. This includes the S0:1, CKE0:1, and ODT0:1 signals.
