Abstract
The Logic Analyzer Probe Board is a hardware design which allows convenient access to signals on a printed circuit board. On one side of the Probe Board assembly is a collection of probes that provide contact to the printed-circuit boards pads, pins, vias and test points on the non-component side of a UUT. The other side of the Probe Board assembly contains an organized collection of connectors, or headers, that connect to a logic analyzer's cable harness. When the Probe Board mates with the printed circuit board, the Probe Board taps into a printed circuit board's signal via the probe-to-pad connection and routes the detected signal via one of the header pins to the logic analyzer. The design of the printed circuit board includes test points that correspond to each signal under test. Once the layout of a printed circuit board is determined, a custom-designed Probe Board may be designed that is cable of accessing each test point.
