The card edge connector of the PCI Active Analysis Probe

module can accommodate one 32 or 64 bit 5V OR 3V PCI add in

card.

The extender card connector is either a 3V or 5V

connector depending on how the board was ordered and

configured at the factory.

Simply align the module with the connector and gently push the

module in until it is seated in the connector. There is sufficient

clearance for the add-in card front plate. The PCI Active Analysis

Probe/PCI add-in card combination can then be installed in any

slot of the PCI Local bus. For mechanical stability the PCI Active

Analysis Probe front plate should be secured to the PCI target

system chassis.

When removing the PCI add-in card from the card edge extender

connector grasp the PCI Active Analysis Probe with one hand

and the PCI add-in card with the other. Gently rock the PCI add-

in card until it is free from the connector.

The nature of an extender card is that it extends the etch length

of the bus. Due to the sensitivity of most PCI designs, extending

the etch length can interfere with the PCI add-in card operation.

Operation of the PCI add-in card when installed in the card edge

extender connector is not guaranteed.

Please check your

system design if you experience failures due to poor signal

fidelity.

The etch from the PCI local bus is routed directly from the PCI

local bus to the extender card connector. Although the etch is

connected to the input of the PCI Active Analysis Probe input

buffers, the extender card connector is NOT buffered from the

PCI local bus.

Please Note: If the Analysis Probe is plugged into the PCI

bus and the logic analyzer is not powered up, the input

buffers on the Analysis Probe will create a low impedance

path to ground thus inhibiting the PCI local bus and any

card in the extender card connector from working.

The PCI bus is extended up from the gold fingers to the input of

the IDT162260 buffers. From the buffer input the etch goes

directly to the extender card connector. The buffer input provides

a clamping diode. The etch is extended approximately 5 inches

from the gold fingers and is on the inner most layer of the board.

There are no via’s on this inner layer in order to give this etch a

direct route.

One issue that has been encountered with using the extender

card connector is that the buffers need power in order to provide

a high impedance to the signal. This means that the logic

analyzer must be attached to the Analysis Probe and powered

up. The PCI Active Analysis Probe module itself is a universal

card. It can operate in either a 5V or 3V PCI system.
