Abstract
Devices, systems, and methods for verifying integrity of a signal path across an isolation barrier are discloses. The devices, systems, and methods insert a marker signal into the signal path across the isolation barrier. The marker includes an analog signal. The devices, systems, and methods transmit a version of the marker signal across the isolation barrier and receiving a signal comprising the transmitted version of the marker signal. The devices, systems, and methods verify the integrity of the signal path based on the received signal.
