The CurveBug debugging hardware is a simple but effective tool to help find faults in modern, arbitrarily complex circuit boards. A time-honored technique is to use a curve tracer on an un-powered board to hunt for anomalies. Curve tracers are expensive, fussy to operate and easily liable to damage the circuit if mis-used. An idea emerged to make a simple and safe debugger based on the curve tracing concept.
If you simultaneously probe the voltage/current relationship (curve) of good versus bad, you get even more insight into any differences between two circuits. In many cases you may have multiple identical circuits in the same product as in a stereo amplifier with one channel faulty can be compared to itself.
The CurveBug interfaces via USB to a Windows PC. It drives a weak signal onto the tested devices with the result graphically displayed on the PC. The CurveBug ground is connected directly to the controlling PC’s ground mitigating ESD hazards. It only operates on devices that are unpowered.
