P6467 High-Speed Probe Adapter Instruction Manual
If you use the DIV2 mode, your logic analyzer must have two 92A96 Modules.
Each module must contain one, two, or three 92A96 acquisition cards. One of
the 92A96 Module samples data on the rising edge of the clock while the other
samples data on the falling edge of the clock.
You must connect two probe cables to each of the J100 and J200 connectors on
the P6467 probe. Each pair of probe cables must connect to the same relative
position and color-coded connector of each 92A96 Module.
You must also define which P6467 probe acquires the Master clock signal. The
flex cable assembly connecting to J400 of that probe is defined as the Master
Clock channel and acquires the clock signal.
You can only acquire one clock signal in the DIV2 operating mode. This clock
signal is distributed to each of the acquisition cards in the module. If your
application requires three-card modules, you must use a clock distribution cable
to connect from the Master Clock probe to a second P6467 probe as shown in
Figure 3 on page 5. The second P6467 probe provides the clock for the last
acquisition card in the module.
In addition to the hardware and clocking requirements, the following setup
requirements exist:
H
Both modules need to be set to the same trigger program and assert a signal
that the other module monitors. (See Figure 8 on page 11 for an example of a
sample trigger program.)
H
The Clock menu setup requires that each module uses the same clock with
one module sampling data on the rising edge of the clock while the other
module samples data on the falling edge of the clock.
When you use the clock from the Master Clock channel, the clock distribution is
essentially the same in the NORM and DIV2 operating modes.
For single-card modules, you must place the MSTR CLK/EXT jumper in the
MSTR CLK position. When the jumper is in the MSTR CLK position, the clock
drivers connect the Master clock to the probe cables connected to J200.
For two-card modules, you must place the CLK A/MSTR CLK jumper in the
MSTR CLK position.
For three-card modules, you must use two P6467 Probes to properly distribute
the clock signal on the probe. Place the CLK A/MSTR CLK jumper in the
MSTR CLK position on the Master Clock probe. Use one of the external clock
connectors, J9 or J10, to drive a second P6467 Probe. Connect a clock cable
from J9 or J10 of the Master Clock probe to the EXT CLK IN connector on the
second P6467 Probe. You must also place the MSTR CLK/EXT jumper of the
second probe in the EXT position.
