Here is a simple but very useful component tester you can build to use with your scope set to the X-Y mode. Some scopes even have this feature incorporated into it.
The transformer can be a small mains to 6.3v ~ 9v type. From my diagram you can see the different components I tested in the simulator for various combinations by closing switches. This tester may also be used to check components in-circuit (with the power off to the circuit under test) with the display showing the result of the components between the two nodes, touched with the test leads.
There are many more shapes from combination of components, and the user can easily log his own"signatures" of known combinations for later reference. This is very handy when faultfinding many of the same product or circuit.
