DDR3THIN-MN-XXX 13 Doc. Rev. 1.11
TLA Master
Connect the NEX-PRB1X-T “C” probe head to DDR3 Interposer’s LEASH (soldered-on
coax cable) that is attached to “M_C” position on the Interposer.
Connect the NEX-PRB2X-T A3/2 & A1/0 probe head to DDR3 Interposer’s LEASH
that is attached to “M_ A3/2 A1/0” position on the Interposer.
Connect the NEX-PRB1X-T “E” probe head to the NEX-PRBCOAX.
Note the leads 9- 12 of the NEX-PRBCOAX must be connected to the second slots Chip
Select lines (CS) near the second and third DIMM socket, usually on the back of the
mother board.
Match the label on the end of the NEX-PRB1X-T/2X-T probes with the labels on the
front of the Tektronix Logic Analyzer Master module and connect.
TLA Slave
Connect the NEX-PRB2X-T A3/2 & A1/0 probe head to DDR3 Interposer’s LEASH
that is attached to “S_ A3/2 A1/0” position on the Interposer.
Connect the NEX-PRB2X-T “C3/2” & “E3/2” probe head to DDR3 Interposer’s LEASH
that is attached to “S_C3/2 E3/2” position on the Interposer.
See Figure 1 for connections. Table 2 shows the Channel Grouping / Wiring for use with the
B_DDR3D_2G support.
3.4 B_DDR3D_3A Support
To acquire DDR3 Read and Write data from a two DIMM slots, for total memory channel
disassembly, at speeds up to 1066MT/s requires three merged TLA7BB4 136-channel, with
1.4G state option, acquisition cards and the use of the B_DDR3D_3A optional support software.
The Master card will be in the lower numbered, of the three cards. Slave card #1 will be in the
adjacent high-numbered slots. Slave card #2 will be in the adjacent low-numbered slots. This
support also requires two NEX-DDR3INTR-THIN Interposer products.
The logic analyzer
modules should be connected to the DDR3 DIMM Interposer as follows using (5) NEX-
PPRB1X-T probes and three (3) NEX-PRB2X-T probes:
