Probe Adapter Description
The probe adapter is nonintrusive hardware that allows the logic analyzer to
acquire data from a microcontroller 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 144 pin EIAJ QFP test clip that attaches to the
microcontroller and the probe adapter circuit board that contains circuitry to
buffer the signals and bus switching electronics. The probe adapter connects to
the microcontroller in the SUT. Signals from the microcontroller-based system
flow from the probe adapter to the channel groups and through the probe signal
leads to the logic analyzer module.
All circuitry on the probe adapter is powered from the supplied power adapter.
The probe adapter accommodates the Siemens SAB-C167 microcontroller in a
144-pin metric PQFP package.
