The PCI Active Analysis Probe is a universal PCI short card that 
attaches to  Agilent logic analyzers.  The Analysis Probe has five 
major parts: 

1.  The input buffers 

2.  The latching buffers 

3.  The interface to the logic analyzer 

4.  The clocking and cycle bit generation logic 

5.  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 to 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.
