How do you test a transistor using cathode ray oscilloscope?

Yeah...its possible to test the transistor using Cathode Ray Oscilloscope (CRO).

CRO provides a function called "Component Testing". Just connect the transistor terminals between two pins provided by this function and you can observe the patterns on the CRO screen.

Normally, in case of transistor, The operation is divided in few parts.

01. Observe the pattern for CB configuration.

---- For this, connect the terminalsfrom CRO between this Collector and Base terminals and you can observe the pattern shown by CRO.

Same procedure should continue for CE & BE configuration so as to test the transistor.
