Application Notes
Diagnosing Faulty Relays in a Switch Matrix
Relay switch matrix instruments do not generally provide a way of verifying the integrity of the relays that make up the matrix. So, how can you tell if there are shorts between adjacent paths? Or shorts to ground or some other voltage level?
Measuring continuity on a specific path does not guarantee that the path is not shorted to an adjacent path. How many matrix paths can you test at once to ensure isolation?
