Probe Adapter Description

The probe adapter is nonintrusive hardware that allows the logic analyzer to
acquire data from a microprocessor in its own operating environment with little
effect, if any, on that system. Information on basic operations contains a figure
showing the logic analyzer connected to a typical probe adapter. Refer to that
figure while reading the following description. 

The probe adapter consists of a circuit board and two sockets for a Socket 7
microprocessor. The probe adapter connects to the microprocessor in the system
under test. Signals from the microprocessor-based system flow from the probe
adapter to the channel groups and through the probe signal leads to the module.

All circuitry on the probe adapter is powered from the supplied power adapter.

The probe adapter accommodates the Intel Pentium, low-power embedded
Pentium with MMX technology, and Socket 7 microprocessors devices.
