The PCI Active Analysis Probe is a universal PCI short card that

attaches to Agilent logic analyzers. The Analysis Probe has five

major parts:

The input buffers

The latching buffers

The interface to the logic analyzer

The clocking and cycle bit generation logic

The extender card connector

The input buffers present a single electrical load on the PCI bus

and are made up of IDT162260 tri-port buffers. The PCI clock is

buffered by a Motorola 807 high speed clock buffer.

When the Analysis Probe is in Timing mode output Port 2 of the

tri-port

buffers

goes

directly

the

logic

analyzer

input

terminators.

When in State mode output Port 2 is tri-stated.

Output port 1 is always enabled and goes to the latching buffers.
