Upgrade to make printed circuit board diagnostics #4
Description
Hello, Congratulations on the project!
The new maintenance means has a database of printed circuit boards that work correctly for comparison with damaged or altered printed circuit boards.
Unfortunately access to this type of tools is very limited due to the cost of acquisition because the developers charge very expensive.
I've been verifying that the simplest diagnostic mode makes use of a system similar to an oscilloscope in XY mode.
A sinusoidal signal is applied to the circuit while it is monitored by the oscilloscope in xy mode. The image (or its data) is stored for future comparison.
I think a good signal generator would be the AD9850.

This is an adapter for plotting component curves, so I understand, it's a part of the diagnostic circuit.
Wave Generator + Adapter + XY Oscilloscope + Database + Comparison = Diagnosis System.
An example of this type defect locator can be seen in this video below:

Is it possible to add a database and comparison in the processing code?
