Optional Auxiliary PCI connector
The PCI Bus Analyzer Card incorporates a PCI connector on top which extends the
system PCI bus and allows other PCI cards to be plugged into the analyzer for
development or production testing. This feature allows the analyzer to monitor the
same point-to-point signals such as REQ# & GNT# on the card under test without
requiring any external connections. In this mode, both the analyzer and the card under
test require only one PCI slot. Special design methodology has been incorporated to
minimize any reflections, delay or cross-talk.
The top connector is intended for monitoring use as an analyzer only and could
interfere with the exerciser. The TA700 has an On-board arbiter that allows the TA700
to be a master regardless of the board type installed in the top connector. It is
recommended that there not be 2 masters in the same slot.
Note: This feature only exists on the TA700 and TA700PDC PCI analyzer and not on the
TA700C, TA800 or TA850 versions.
Figure 2 illustrates such a test setup. An On-Off switch on the analyzer card enables
and disables the power and signal connections between the system and the card under
test allowing rapid cycling of the test cards without shutting off the system power.
Caution: The TA700 will not work with the top connector when operated at 100 MHz bus
speed. It is not recommended to operate the TA700 with the extender at frequencies
above 66 MHz, the extender switch must be in the Off position.
