P6467 High-Speed Probe Adapter Instruction Manual
The purpose of each connector on the probe follows:
H
J6 (EXT CLK IN). Use this clock input connector when you derive the clock
from another P6467 Probe that has been defined as the master clock.
H
J7, J8 (MASTER CLOCK DELAY). Use these two connectors to delay the
clock transition with longer lengths of 75
cables relative to the data signal
transitions (if needed) to meet the setup and hold timing requirements for the
logic analyzer.
H
J9 (MSTR CLK OUT1), J10 (MSTR CLK OUT2). Use these two connectors
if your logic analyzer module needs more than two acquisition cards. These
connectors distribute the clock to other P6467 Probes while preserving the
timing relationship between the master clock and data on other probes. Use
only the clock cable that came with your probe, otherwise the timing
relationship can not be guaranteed.
H
J300 (INPUT DATA A). This connector is the Data A clock and data input
flex connector. The flex cable directs the signals from the system-under-test
to the J100 Output Data connector (top two probe connectors) The clock
signal from this connector is designated as the CLK A signal at J3.
H
J400 (INPUT DATA B). This connector is the Master clock and data input
flex connector. This flex cable assembly is designated as the Master clock
input for the probe; only the clock input on this flex cable can be designated
as the Master clock. The flex cable directs the signals from the system-un-
der-test to the J200 Output Data connector (bottom two probe connectors).
H
J100 (OUTPUT DATA A). This connector is the Data A clock and data
output connector. The top two 50-pin connectors connect to the 92A96
ribbon or coaxial cable connectors.
H
J200 (OUTPUT DATA B). This connector is the Master clock and data
channel output connector. The bottom two 50-pin connectors connect to the
92A96 ribbon or coaxial cable connectors.
H
J5 (Probe Power). The probe power cable connects to the probe at J5. The
probe receives its power from the power connector of the acquisition module
in the logic analyzer.
Descriptions and Locations of Jumpers
Figure 13 shows the locations of the jumpers on the P6467 probe. The jumper
positions determine the operating mode and clocking of the probe. The probe
defined as the Master Clock probe must have the jumpers in the correct positions
to operate correctly; the jumper positions have no impact on probes not acquiring
clock signals.
