component in the cartridge for home - based - gaming
bridge that allows for interactive play via the internet

Explanation:

An oscilloscope is an electrical device. It works by showing electrical signals as visual waveforms on a screen, similar to how a radar screen displays information. It is not a component in a home - based gaming cartridge (those usually have chips with game data), not a bridge for internet - based interactive play (that's more related to network hardware), and not a part of button controllers (controllers have buttons, joysticks etc. but not oscilloscope - like functionality).

Answer:

electrical device similar to a radar screen
